Description

Technical Field

[0001] The embodiments of this utility model relate to the field of clamping tooling technology, specifically to a clamping device for processing exhaust gas from heat collection pipes. Background Technology

[0002] All-glass heat pipe, also known as all-glass double-vacuum solar collector tube, is usually simply called a collector tube. The collector tube is generally made of high-transmittance high borosilicate ultra-hard glass tube, which is processed by special technology. It is an integral part of inner and outer double-layer tube and single-layer tube, with a high-vacuum interlayer between the inner and outer tubes.

[0003] During the production of solar collector tubes, a heating and venting process is performed. After venting, the tail nozzle tube needs to be electrically sealed (by electrically heating the glass tube to cut it and seal the break). During operation, the solar collector tube is placed on top of a lifting fixture, the tail nozzle tube is inserted into the positioning hole of the electric sealing component, and the glass tube is clamped and fixed. After the solar collector tube is in place, it is heated. The glass tube on the solar collector tube expands due to heat, causing it to shift on the lifting fixture. This can easily result in scratches at the clamping points, leading to substandard product appearance. At the same time, the expansion of the glass tube can cause the tail nozzle tube to shift, resulting in interference at the edge of the positioning hole of the electric sealing component, which can lead to abnormal breakage of the tail nozzle tube and defective products, increasing the defect rate. Therefore, it is necessary to improve and optimize the existing technology to reduce the problems mentioned above. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a clamping device for processing exhaust gas from heat collection tubes, which solves the problem that when heat collection tubes are heated and exhaust gas, the glass tube expands due to heat and rubs against the lifting fixture, causing scratches on the appearance of the glass tube.

[0005] According to one aspect, at least one embodiment of the present invention provides a clamping device for processing exhaust gas from a heat collector tube, comprising:

[0006] Workbench;

[0007] Two lifting frames are arranged in parallel on the workbench. Each lifting frame has several grooves arranged at intervals for placing workpieces. A layer of rock wool is provided in the grooves for contacting the workpieces.

[0008] For example, in at least one embodiment of the present invention, the clamping device for processing exhaust pipes of the heat collection tube has a vertically penetrating sliding hole on the worktable, and the workpiece has a tail nozzle tube. The clamping device further includes:

[0009] An electro-sealing component is slidably disposed within the sliding hole. The electro-sealing component has a sealing through hole. The electro-sealing component is configured to slide upwards until the tail nozzle tube on the workpiece is inserted into the sealing through hole, thereby electro-sealing the tail nozzle tube.

[0010] For example, in at least one embodiment of the present invention, the clamping device for processing exhaust pipes of the heat collection tube has a suspension part on the lower end face of the worktable and further includes a transmission unit, the transmission unit comprising:

[0011] The rocker arm is mounted on the suspension part and located below the electro-sealable component, and the end of the rocker arm near the electro-sealable component has a through groove.

[0012] A pivot pin is rotatably disposed at the lower end of the electro-sealing component and slidably disposed within the groove.

[0013] When the rocker arm is configured to swing upward, it drives the pivot pin and the electro-sealing component in the groove to slide upward synchronously, so that the sealing through hole sleeve covers the outer ring of the tail nozzle tube.

[0014] For example, in the clamping device for processing exhaust pipes provided in at least one embodiment of the present invention, the lower end of the workbench and located on the side of the electro-sealing component has a guide portion, the guide portion has a guide through hole, and the electro-sealing component has a guide rod that is slidably disposed in the guide through hole.

[0015] For example, in at least one embodiment of the present invention, the clamping device for processing exhaust pipes of the present invention has a receiving groove at the end of the lifting arm away from the electro-sealing component, and the transmission unit further includes:

[0016] An extension arm is horizontally rotatably disposed within the storage slot. The extension arm is configured such that after rotating away from the storage slot, the extension arm is located at the end of the rocker arm, and is used to extend the overall length of the rocker arm to increase the length of the rocker arm's lever arm.

[0017] For example, in at least one embodiment of the present invention, the clamping device for processing exhaust pipes of the present invention has a locking arc portion on the lifting arm, and a locking groove on the outer periphery of the locking arc portion; the clamping device further includes a locking unit, the locking unit comprising:

[0018] The locking member is slidably disposed on the suspension part and located above the locking arc part. When the locking member is configured to slide downward, it is engaged in the locking groove to fix the relative positions of the rocker arm, the pivot pin, and the electro-sealable part.

[0019] For example, in at least one embodiment of the present invention, the clamping device for processing exhaust pipes of the present invention further includes:

[0020] A locking spring, with one end acting on the suspension part and the other end acting on the locking member, provides a force to push the locking member closer to the locking groove.

[0021] For example, in at least one embodiment of the present invention, the clamping device for processing the exhaust of the heat collection tube further includes an unlocking unit, which includes:

[0022] The unlocking arm is swung and mounted on the extended arm.

[0023] The unlocking rope is connected at one end to the unlocking arm and at the other end to the top of the locking component;

[0024] A rope loop is fitted onto the unlocking rope, with one end of the rope loop fixed to the extension arm and the other end of the rope loop fixed to the suspension part;

[0025] The unlocking arm is configured to swing and cause the unlocking rope to slide along the rope loop, so that the locking member slides upward and leaves the locking groove.

[0026] For example, in at least one embodiment of the present invention, the clamping device for processing the exhaust of the heat collection tube further includes a plurality of end-lifting units, each of which includes:

[0027] An end bracket is slidably mounted on the worktable and is used to support one end of a single workpiece;

[0028] A pressure sensor is mounted on the end bracket, electrically connected to an external control host, and used to input the collected information into the control host;

[0029] The buffer element has one end acting on the pressure sensor and the other end acting on one end face of the workpiece. It is used to convert the expansion and deformation of the workpiece caused by heat into pressure and transmit it to the pressure sensor.

[0030] A linear driver, disposed on the worktable, is configured to receive and execute command signals from the control host to provide driving force for sliding the end bracket.

[0031] For example, in at least one embodiment of the present invention, a clamping device for processing exhaust pipes is provided, wherein the buffer member is provided with a rubber pad for abutting against the end of the workpiece.

[0032] The beneficial effects of the embodiments of this utility model are as follows:

[0033] In this invention, the sliding hole provides a precise sliding path for the electro-sealing component, ensuring its stability during vertical sliding and preventing offset or wobbling. After the workpieces are placed in batches, the tail nozzle is inserted into the sliding hole, and then the electro-sealing component is driven to slide upwards. If misalignment between the tail nozzle and the sealing through-hole is found during the process, the position of each individual workpiece can be adjusted individually, reducing the amount of workpiece adjustment. This ensures that the sealing through-hole is accurately aligned with the tail nozzle, improving the precision of the electro-sealing operation. The sliding fit design between the electro-sealing component and the sliding hole allows the electro-sealing component to be flexibly adjusted as needed, facilitating rapid electro-sealing operation after the heat collector tube is placed in place, thus improving processing efficiency.

[0034] During the thermal expansion of the workpiece, the position of the tail nozzle tube will shift. By setting the inner diameter of the sealing hole to be larger than the outer diameter of the tail nozzle tube on the heat collector tube workpiece, the shift in the position of the tail nozzle tube can be absorbed, avoiding interference between the tail nozzle tube and the edge of the sealing hole, reducing the occurrence of abnormal breakage of the tail nozzle tube, and lowering the product defect rate.

[0035] The sliding structure of the electro-sealing component works in conjunction with the groove and rock wool layer on the support frame to ensure the stability of the heat collection tube during the heating process and the accuracy of the electro-sealing operation of the tail nozzle tube. This effectively solves the problems in related technologies and improves the production quality and efficiency of the heat collection tube. Attached Figure Description

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0044] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

Therefore, they should not be construed as limitations on this utility model.

[0048] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] like Figures 1-5 As shown, this invention illustrates a clamping device for processing exhaust pipes in one embodiment of the present invention. The worktable 1 of the clamping device is flat, with two lifting frames 2 arranged parallel to each other on its upper surface. Each lifting frame 2 has several grooves 21 arranged at intervals on its upper surface. The grooves 21 have an arc-shaped cross-section and are used to place the exhaust pipe workpiece 91. A rock wool layer 22 is provided on the inner wall of each groove 21, covering the entire inner surface of the groove 21 and fitting tightly against the inner wall of the groove 21.

[0050] When the collector tube workpiece 91 is placed in the groove 21, the outer surface of the workpiece 91 abuts against the outer surface of the rock wool layer 22, which provides support and cushioning for the workpiece 91. During the heating and exhaust process of the collector tube, the workpiece 91 expands due to heat. Because the rock wool layer 22 has a certain degree of elasticity and softness, it can deform with the expansion of the workpiece 91, avoiding hard friction with the outer surface of the workpiece 91 and maintaining stable support for the workpiece 91.

[0051] The groove 21 on the support frame 2 provides a stable placement position for the heat collector tube workpiece 91, ensuring that the workpiece 91 maintains the correct posture during processing and preventing it from shaking or shifting. The rock wool layer 22 creates a flexible contact between the support frame 2 and the outer surface of the workpiece 91, effectively avoiding the friction problem that occurs when the workpiece 91 expands, as is common with traditional rigid support structures. This prevents scratches on the glass tube's appearance and improves the product's appearance quality. The elastic properties of the rock wool layer 22 allow it to adapt to the expansion and contraction of the workpiece 91 during heating, maintaining stable support and ensuring the stability of the heat collector tube during processing. The synergistic effect of the groove 21 and the rock wool layer 22 ensures the positioning accuracy of the heat collector tube and avoids damage to the surface of the workpiece 91 during processing. This solves the problem of easily scratched glass tubes during heat collector tube heating and exhaust in related technologies, reducing product defect rates and improving production efficiency and product quality.

[0052] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 1-2 and Figures 4-5 As shown, the worktable 1 of the clamping device for processing the heat collector tube exhaust has a vertically penetrating sliding hole 11, the inner wall of which is a smooth plane. The electro-sealing component 3 has a cylindrical structure, its outer circumferential surface slidingly engaging with the inner wall of the sliding hole 11, allowing it to slide up and down along the sliding hole 11. A vertically penetrating sealing through hole 31 is provided at the axial position of the electro-sealing component 3, the inner diameter of which is larger than the outer diameter of the tail nozzle 92 on the heat collector tube workpiece 91. The electro-sealing component 3 is selected from existing sealing device combinations that can electrically heat the glass tube and cut off and seal the tail nozzle 92 on the workpiece 91.

[0053] When it is necessary to perform an electro-sealing operation on the tail nozzle tube 92 of the collector tube, the electro-sealing component 3 is driven to slide upward along the sliding hole 11 until the tail nozzle tube 92 is inserted into the sealing through hole 31. The electro-sealing component 3 performs electro-sealing treatment on the tail nozzle tube 92 through the sealing through hole 31, so that the tail nozzle tube 92 is cut off at high temperature and the cut is sealed.

[0054] In the existing technology, workpieces 91 are generally loaded in batches, and the position of the tail nozzle tube 92 on the heat collector tube workpiece 91 is deviated. If the tail nozzle tube 92 interferes with the sealing through hole 31 during the process of workpiece 91 loading, a batch of workpieces 91 needs to be moved out at the same time, the corresponding tail nozzle tube 92 needs to be adjusted, and then the workpieces are reloaded, which is a cumbersome process. After the improvement, the sliding hole 11 provides a precise sliding path for the electric sealing component 3, ensuring that the electric sealing component 3 remains stable during the up and down sliding process and avoiding deviation or shaking. After the workpieces 91 are placed in batches, the tail nozzle tube 92 is inserted into the sliding hole 11, and then the electric sealing component 3 is driven to slide up. If it is found that the tail nozzle tube 92 is not aligned with the sealing through hole 31 during the process, the position of a single workpiece 91 can be adjusted individually, reducing the adjustment amount of workpiece 91. This ensures that the sealing through hole 31 can be accurately aligned with the tail nozzle tube 92, improving the accuracy of the electric sealing operation. The sliding fit design between the electro-sealing component 3 and the sliding hole 11 allows the electro-sealing component 3 to be flexibly adjusted as needed, facilitating rapid electro-sealing operation after the heat collection tube is placed in place, thus improving processing efficiency.

[0055] During the thermal expansion of workpiece 91, the position of the tail nozzle tube 92 will shift. By setting the inner diameter of the sealing through hole 31 to be larger than the outer diameter of the tail nozzle tube 92 on the heat collector tube workpiece 91, the shift in the position of the tail nozzle tube 92 can be absorbed, avoiding interference between the tail nozzle tube 92 and the edge of the sealing through hole 31, reducing the occurrence of abnormal breakage of the tail nozzle tube 92, and lowering the product defect rate.

[0056] The sliding structure of the electro-sealing component 3 works in conjunction with the groove 21 and rock wool layer 22 on the support frame 2 to ensure the stability of the heat collection tube during the heating process and the accuracy of the electro-sealing operation of the tail nozzle tube 92. This effectively solves the problems in related technologies and improves the production quality and efficiency of the heat collection tube.

[0057] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 1-2 and Figures 4-5 As shown, the lower end face of the worktable 1 of the clamping device for processing the exhaust of the heat collector tube is provided with a suspension part 12. The suspension part 12 has a plate-like structure, and its upper end face is fixedly connected to the lower end face of the worktable 1. The middle part of the rocker arm 41 is oscillating up and down on the suspension part 12 by a pin in the prior art, and is located below the electro-sealing component 3. A through groove 42 is opened at the end of the rocker arm 41 near the electro-sealing component 3, and the groove 42 extends along the length direction of the rocker arm 41.

[0058] A pivot pin 43 is provided at the lower end of the electro-sealing component 3. The two ends of the pivot pin 43 are rotatably disposed on both sides of the lower end of the electro-sealing component 3, and the middle part of the pivot pin 43 is slidably disposed in the slide groove 42. When the rocker arm 41 swings upward, the inner wall of the slide groove 42 pushes the pivot pin 43 to move upward, and the pivot pin 43 drives the electro-sealing component 3 to slide upward synchronously, so that the sealing through hole 31 is fitted over the outer ring of the tail nozzle tube 92.

[0059] The suspension unit 12 provides a stable support point for the rocker arm 41, ensuring that the rocker arm 41 can reliably swing up and down on the worktable 1. The cooperative design of the rocker arm 41 and the pivot pin 43 converts the swinging motion of the rocker arm 41 into the linear motion of the electro-sealing component 3, realizing precise up and down sliding control of the electro-sealing component 3, so that the sealing through hole 31 can be accurately aligned with the tail nozzle tube 92, improving the accuracy of the electro-sealing operation. The setting of the slide groove 42 provides sliding space for the pivot pin 43, allowing the rocker arm 41 to smoothly drive the electro-sealing component 3 during swinging, avoiding jamming during movement, and ensuring the stability and reliability of the equipment.

[0060] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 1-2 and Figures 4-5 As shown, a guide portion 13 is provided at the lower end of the worktable 1 of the clamping device for processing the heat collector tube exhaust, and on one side of the electro-sealing component 3. The guide portion 13 has a plate-like structure, and its upper end face is fixedly connected to the lower end face of the worktable 1. A guide through hole is provided on the guide portion 13, and the axis of the guide through hole is parallel to the sliding direction of the electro-sealing component 3.

[0061] A guide rod 32 is provided on one side of the electro-sealable component 3. One end of the guide rod 32 is fixedly connected to the electro-sealable component 3, and the other end is slidably disposed in the guide through hole. When the electro-sealable component 3 slides up and down under the drive of the rocker arm 41, the guide rod 32 slides synchronously in the guide through hole, thus guiding the sliding of the electro-sealable component 3.

[0062] The guide section 13 and guide rod 32 provide precise guidance for the sliding of the electro-sealing component 3, ensuring that the electro-sealing component 3 maintains a straight line during its up-and-down sliding process, avoiding deviation or wobbling. This ensures that the sealing through-hole 31 can be accurately aligned with the tail nozzle tube 92, improving the accuracy of the electro-sealing operation. The sliding cooperation between the guide rod 32 and the guide through-hole reduces the frictional resistance during the sliding process of the electro-sealing component 3, making its movement smoother and improving the operating efficiency of the equipment. This guiding structure enhances the stability of the electro-sealing component 3, enabling it to withstand greater external forces during operation without deformation or damage, extending the service life of the equipment. The synergistic effect of the guide section 13 and guide rod 32 further optimizes the movement trajectory of the electro-sealing component 3, ensuring the accuracy and reliability of the electro-sealing operation, effectively solving the problems that easily occur during the electro-sealing of the tail nozzle tube 92 in related technologies, and improving the production quality and efficiency of the heat collection tube.

[0063] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 1-2 and Figures 4-5 As shown, the end of the lifting arm 41 of the clamping device for processing the exhaust of the heat collector tube is provided with a receiving groove 44 away from the electric seal 3. The receiving groove 44 extends through the lifting arm 41 along its width direction. One end of the extended arm 45 is horizontally rotatably mounted in the receiving groove 44 by a pin in the prior art. The axis of the pin is perpendicular to the swing axis of the lifting arm 41.

[0064] When the extension arm 45 rotates outward away from the storage slot 44 until it aligns with the length direction of the rocker arm 41, the extension arm 45 is located at the end of the rocker arm 41, serving to extend the overall length of the rocker arm 41. When the extension arm 45 rotates inward toward the storage slot 44 until it aligns with the length direction of the rocker arm 41, the extension arm 45 is stored within the storage slot 44.

[0065] The storage slot 44 provides storage space for the extension arm 45, allowing it to be stored inside the lifting arm 41 when not in use, reducing the space occupied by the equipment and facilitating transportation and storage. The rotatable design of the extension arm 45 allows for flexible position adjustment as needed. When the lever arm length of the lifting arm 41 needs to be increased, the extension arm 45 can be rotated out of the storage slot 44, extending the overall length of the lifting arm 41 and thus increasing its lever arm. This allows operators to drive the lifting arm 41 to swing with less force, reducing operational difficulty. By adjusting the position of the extension arm 45, the lever arm length of the lifting arm 41 can be changed, thereby achieving precise control over the rising height of the electro-sealing component 3 and improving the accuracy of the electro-sealing operation. This adjustable structural design enhances the adaptability of the equipment. The synergistic effect of the extension arm 45 and the storage slot 44 effectively improves the performance and ease of operation of the equipment without increasing its complexity, further optimizing the processing technology of the heat collection tube.

[0066] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 4-5 As shown, the outer periphery of the lifting arm 41 of the clamping device for processing the exhaust of the heat collector tube is provided with a locking arc portion 46. The locking arc portion 46 has an arc-shaped structure, and its center coincides with the swing axis of the lifting arm 41. Several locking grooves 47 are opened on the outer peripheral surface of the locking arc portion 46, and the locking grooves 47 are evenly distributed along the circumferential direction of the locking arc portion 46.

[0067] A locking unit 5 is provided on the suspension part 12 of the workbench 1. The locking unit 5 includes a locking member 51, which is slidably mounted on the suspension part 12 through the cooperation of a rod and a hole, and is located above the locking arc part 46. The lower end of the locking member 51 has a protruding structure that matches the locking groove 47.

[0068] When the rocker arm 41 swings upward to the predetermined position, the locking member 51 slides downward, and the protruding structure at its lower end engages in the locking groove 47, thereby fixing the relative positions of the rocker arm 41, the pivot pin 43 and the electric seal 3.

[0069] The locking arc 46 and locking groove 47 provide multiple positioning points for the rocker arm 41, enabling it to lock at different swing angles and meeting the processing requirements of different specifications of heat collection tubes. The engaging structure between the locking element 51 and the locking groove 47 effectively prevents the rocker arm 41 from shaking or shifting during operation, ensuring the stability of the electro-sealing component 3 during electro-sealing operation and improving processing accuracy. By fixing the relative positions of the rocker arm 41, the pivot pin 43, and the electro-sealing component 3, the locking unit 5 ensures the alignment accuracy between the sealing through hole 31 and the tail nozzle tube 92, avoiding interference between the tail nozzle tube 92 and the edge of the positioning hole, reducing the occurrence of abnormal breakage of the tail nozzle tube 92, and lowering the product defect rate. The locking unit 5 enhances the reliability of the equipment, enabling it to maintain a stable working state during long-term operation, reducing the number of maintenance operations and repair costs.

[0070] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 4-5 As shown, the locking unit 5 of the clamping device for processing the exhaust of the heat collector tube also includes a locking spring 52. One end of the locking spring 52 acts on the suspension part 12, and the other end acts on the locking member 51. The locking spring 52 is always in a compressed state, and the force it provides is used to push the locking member 51 closer to the locking groove 47.

[0071] When the rocker arm 41 swings upward to the predetermined position, the locking spring 52 pushes the locking member 51 downward to slide, so that the lower end of the locking member 51 is engaged in the locking groove 47. When unlocking is required, the locking member 51 is pulled upward against the force of the locking spring 52, so that it is disengaged from the locking groove 47.

[0072] The locking spring 52 provides a continuous pushing force to the locking member 51, ensuring that the locking member 51 can reliably engage in the locking groove 47, effectively preventing the lifting arm 41 from loosening during operation and improving the stability and reliability of the equipment. The elastic characteristics of the locking spring 52 allow it to accommodate minor errors between the locking member 51 and the locking groove 47, ensuring smooth operation of the locking structure and reducing the equipment failure rate. Even after prolonged use, if wear occurs between the locking member 51 and the locking groove 47, the elastic force of the locking spring 52 still ensures a tight fit between them, extending the equipment's service life. The synergistic effect of the locking spring 52, the locking member 51, the locking arc 46, and the locking groove 47 forms a locking system that ensures the stability of the electro-sealing component 3 during operation, further improving the accuracy and quality of the electro-sealing operation of the collector tube tail nozzle 92 and reducing the product defect rate.

[0073] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 1-2 and Figures 4-5 As shown, the unlocking unit 6 of the clamping device for processing the exhaust of the heat collector tube includes an unlocking arm 61, an unlocking rope 62, and a rope loop 63. The unlocking arm 61 is pivotally mounted on the end of the extended arm 45 away from the lifting arm 41 via a pin, and the axis of the pin is parallel to the rotation axis of the extended arm 45. One end of the unlocking rope 62 is fixedly connected to the middle of the unlocking arm 61, and the other end is fixedly connected to the top of the locking member 51. The rope loop 63 is sleeved on the outer periphery of the unlocking rope 62, with one end of the rope loop 63 fixedly connected to the extended arm 45 near the unlocking arm 61, and the other end fixedly connected to the suspension part 12 near the locking member 51. The middle part of the rope loop 63 is fixed to the lifting arm 41 and the suspension part 12 by a rope clip or wire clip in the prior art. Only the ends of the rope loop 63 and the unlocking rope 62 are shown in the figure; the middle part is not shown.

[0074] When unlocking is required, the unlocking arm 61 swings towards the extension arm 45, pulling the unlocking rope 62 to slide along the inside of the rope sleeve 63. The unlocking rope 62 causes the locking member 51 to slide upward, causing the lower end of the locking member 51 to leave the locking groove 47. When the unlocking arm 61 swings away from the extension arm 45, the unlocking rope 62 loosens, and the locking member 51 slides downward under the action of the locking spring 52, re-engaging into the locking groove 47.

[0075] The swing mechanism of the unlocking arm 61 allows the operator to drive the unlocking rope 62 with a smaller force, reducing the force required for unlocking and improving ease of operation. The cooperation between the unlocking rope 62 and the rope sleeve 63 ensures that the unlocking rope 62 moves along a preset path during pulling, preventing interference with other components due to deviation and ensuring the stability of the unlocking action. The guiding effect of the rope sleeve 63 on the unlocking rope 62 ensures precise sliding of the locking component 51, guaranteeing its smooth disengagement from the locking groove 47 and reducing the risk of mechanical jamming. The coordinated action of the unlocking unit 6 and the locking unit 5 enables rapid switching between locking states, ensuring the reliability of locking during electro-sealing and improving the efficiency of the unlocking operation. This avoids processing errors caused by operational delays in traditional manual unlocking methods, further enhancing the stability and pass rate of the electro-sealing process for the heat collector tubes.

[0076] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 1-3 As shown, the worktable 1 of the clamping device for processing the exhaust of the heat collector tube is equipped with several end-lifting units 7. Each end-lifting unit 7 includes an end bracket 71, a pressure sensor 72, a buffer 73, and a linear actuator 74. The upper surface of the worktable 1 is provided with a guide rail commonly used in the prior art. The end bracket 71 is slidably mounted on the worktable 1 through the cooperation of a slider and the guide rail, which is commonly used in the prior art. Each end bracket 71 is used to lift one end of a single heat collector tube workpiece 91. A rock wool layer 22 is provided on the area of ​​the end bracket 71 that abuts against the end of the workpiece 91 to prevent scratches.

[0077] Pressure sensor 72 is mounted on end bracket 71, with its force-bearing side connected to one end of buffer 73. Pressure sensor 72 is also electrically connected to an external control unit (not shown in the figure) to input the collected pressure information into the control unit. The other end of buffer 73 acts on one end face of the heat collector tube workpiece 91. Buffer 73 is a spring, a technology currently available.

[0078] A linear actuator 74 is mounted on the worktable 1, and its power output end is connected to the end bracket 71. The linear actuator 74 is configured to receive and execute command signals issued by the control host to provide the driving force for the sliding of the end bracket 71. The linear actuator 74 is an electrically driven cylinder, which is a technology in the prior art.

[0079] When the heat collector tube workpiece 91 expands due to heat, its end face pushes the buffer 73, which in turn transmits the pressure to the pressure sensor 72. The pressure sensor 72 converts the pressure information into an electrical signal and transmits it to the control host. Based on the received pressure information, the control host sends a corresponding command signal to the linear actuator 74, which then drives the end bracket 71 to slide along the guide rail to accommodate the expansion or contraction of the workpiece 91.

[0080] The sliding arrangement of the end bracket 71 allows it to automatically adjust its position according to the expansion or contraction of the collector tube workpiece 91, avoiding the constraint stress on the workpiece 91 caused by traditional fixed support structures and reducing the risk of the glass tube breaking due to thermal expansion. The pressure sensor 72 enables real-time monitoring of the pressure on the end face of the workpiece 91, allowing the control host to promptly obtain the status information of the workpiece 91 and providing a basis for the precise control of the linear actuator 74. The buffer 73 acts as a buffer between the end face of the workpiece 91 and the pressure sensor 72, avoiding potential damage or indentation from direct contact and improving the measurement accuracy of the pressure sensor 72. The coordinated operation of the linear actuator 74 and the control host enables automatic adjustment of the end bracket 71 position, allowing the equipment to adapt to collector tube workpieces 91 of different specifications and expansion degrees, improving the equipment's versatility and adaptability. This structural design, in conjunction with the previously described groove 21 and rock wool layer 22, further optimizes the support and positioning of the collector tube during the heating process, effectively solving related technical problems and improving the production quality and efficiency of the collector tube.

[0081] In some examples, the structure of the clamping device for processing the exhaust of the heat collector tube is optimized, for example, as... Figures 1-3 As shown, a rubber pad 75 is provided at one end of the buffer member 73 of the clamping device for processing the heat collector tube exhaust, near the workpiece 91. The rubber pad 75 is fixedly connected to the buffer member 73. When the buffer member 73 acts on the end face of the heat collector tube workpiece 91, the rubber pad 75 is in direct contact with the end face of the workpiece 91.

[0082] During the heating and exhaust process of the heat collector tube, the workpiece 91 expands due to heat, and the end face transmits the pressure to the buffer 73 through the rubber pad 75. The elastic properties of the rubber pad 75 allow it to undergo a certain deformation, thereby buffering the impact force between the end face of the workpiece 91 and the buffer 73.

[0083] The rubber pad 75 prevents direct rigid contact between the buffer 73 and the end face of the workpiece 91, effectively preventing damage to the end face of the workpiece 91 caused by the buffer 73 during the expansion of the heat collector tube, thus protecting the integrity of the workpiece 91. The elastic deformation capability of the rubber pad 75 allows it to absorb and disperse the impact force generated by the expansion of the workpiece 91, reducing stress concentration and further lowering the risk of glass tube breakage. This structural design, combined with the previously described end-support unit 7, further optimizes the support and positioning of the heat collector tube during the heating process, ensuring that the equipment can adapt to heat collector tube workpieces 91 of different specifications and expansion degrees, thereby improving the production quality and efficiency of the heat collector tubes.
