Description

Technical Field

[0001] This invention relates to the field of microwave oven magnetron manufacturing technology, and in particular to an automatic calibration fixture for a magnetron anode antenna. Background Technology

[0002] As the core component of a microwave oven, the magnetron is used to emit microwaves; therefore, the magnetron requires a certain degree of precision in its production process, such as the overall airtightness of the connection, the concentricity of the exhaust pipe assembly, and the horizontality of the anode antenna and the cathode terminal.

[0003] In the production process of magnetrons, it is necessary to assemble and weld the various cathode components to form a single cathode, and at the same time assemble and weld the various anode components to form an anode. Then, the cathode and anode are assembled together to form the core of the magnetron. Next, the core is subjected to quality inspection, and only after passing the quality inspection can it be installed and used in a microwave oven.

[0004] Currently, the pass rate of die quality inspection is basically around 80%. A small portion of the defective dies are due to the neglect of the horizontal position between the anode antenna and the cathode terminal during the assembly of the anode and cathode, resulting in the anode antenna and cathode terminal of the die not being flush. The vast majority of the remaining defective dies are caused by defective anodes. The main reason for the defective anodes is that the anode antenna is tilted and not perpendicular to the upper surface of the anode shell.

[0005] To address the issue of tilted anode antennas, the conventional approach is to manually inspect the assembled anode components and correct any defective ones to restore the tilted antenna to its vertical position and make it perpendicular to the top surface of the anode housing. However, because anode antennas are thin and short, it is difficult to clearly determine whether the antenna is tilted by the naked eye in a short time, leading to frequent missed inspections. Furthermore, manual antenna correction is slow and inefficient, significantly delaying the production of anode components and consequently affecting the production of subsequent chips and magnetrons. Based on this, the present invention was designed. Summary of the Invention

[0006] This invention designs an automatic calibration fixture for magnetron anode antennas to replace manual quality inspection of the magnetron anode assembly antenna and actively corrects tilted antennas to restore them to verticality and perpendicularity to the upper surface of the anode shell. The quality inspection and calibration is fast and efficient, which not only improves the production efficiency and yield of the anode assembly, but also further improves the production efficiency and yield of subsequent chips and magnetrons.

[0007] To address the aforementioned problems, this invention discloses an automatic calibration fixture for a magnetron anode antenna, used to calibrate the antenna of the anode assembly of a magnetron. The fixture includes a worktable and a track flatly mounted on the worktable, a sliding mold base mounted on the track, the sliding mold base being slidable along the track, and the anode assembly being mounted on the sliding mold base.

[0008] The workbench is equipped with a first calibration device and a second calibration device for calibrating the antenna. The first calibration device calibrates the antenna from the left and right direction, and the second calibration device calibrates the antenna from the front and back direction.

[0009] When the sliding mold base moves along the track to the calibration position of the first calibration device, it pauses its movement. After the antenna is calibrated by the first calibration device, the sliding mold base continues to move along the track to the calibration position of the second calibration device and pauses its movement to receive calibration from the second calibration device.

[0010] Furthermore, the workbench is also equipped with a pinning device, a fourth calibration device, and a second transfer device;

[0011] The sliding mold base moves along the track from the correction position of the second correction device to the pinning position of the pinning device and then stops moving. The pinning device is used to knock off the center pin of the anode assembly at the pinning position.

[0012] The second transfer device is used to transfer the anode assembly after being de-cored by the de-coring device to the fourth calibration device, and to transfer the anode assembly after calibration by the fourth calibration device to the sliding mold base.

[0013] The fourth calibration device is used to calibrate the antenna.

[0014] Furthermore, the first calibration device includes:

[0015] The first mounting bracket is disposed on the workbench;

[0016] A first linear actuator is mounted on the first mounting bracket; and

[0017] At least two first clamping plates, driven by a first linear actuator, move closer to each other in the left-right direction to clamp the antenna or move further apart to loosen the clamping of the antenna.

[0018] Furthermore, the second calibration device includes:

[0019] The second linear actuator is vertically mounted on the worktable;

[0020] The second linear actuator, driven by the first linear actuator, moves up and down; and

[0021] At least two second clamping plates, driven by the second linear actuator, move closer to each other in the front-back direction to clamp the antenna or move further apart to loosen the clamping of the antenna.

[0022] Furthermore, the second clamping plate is provided with an antenna mast correction groove to accommodate the antenna mast portion.

[0023] Furthermore, the knocking device includes:

[0024] The third linear actuator is vertically mounted on the worktable;

[0025] The third mounting plate moves up and down under the drive of the third linear actuator; and

[0026] The dowel is vertically fixed below the third mounting plate and can be driven by the third linear actuator to press down and knock off the center pin of the anode assembly.

[0027] Furthermore, the fourth calibration device includes:

[0028] The fourth mounting bracket is located on the workbench;

[0029] The fourth linear actuator is mounted on the fourth mounting bracket;

[0030] At least two fourth clamping plates, driven by a fourth linear actuator, move closer to each other in the left-right direction to clamp the antenna or move further apart to loosen the clamping of the antenna;

[0031] The lifting mold base, located below the fourth clamping plate, is used to receive the anode assembly delivered by the second transfer device; and

[0032] The lifting device is used to push the lifting mold base upward so that the antenna can be clamped and corrected by the fourth clamping plate.

[0033] Furthermore, the fourth clamping plate is provided with an antenna flat end correction groove to accommodate the flat end of the antenna.

[0034] Furthermore, the second transfer device includes:

[0035] At least two fifth-ply plates;

[0036] The fifth linear actuator is used to drive the two fifth clamping plates to move closer to each other in the front-back direction to clamp the anode housing of the anode assembly or to move away from each other to loosen the clamping of the anode housing;

[0037] The fifth linear actuator three is used to drive the fifth linear actuator four to move up and down;

[0038] The second linear actuator is used to drive the third linear actuator to move left and right; and

[0039] The fifth linear actuator is used to drive the fifth linear actuator to move back and forth.

[0040] Furthermore, the track includes a left track and a right track arranged in parallel, and the sliding mold base slides in opposite directions on the left track and the right track;

[0041] The automatic calibration fixture also includes a transfer device 1 located at both ends of the left and right tracks. One transfer device 1 is used to transfer the sliding mold base that has slid to the end of the left track to the right track, and the other transfer device 1 is used to transfer the sliding mold base that has slid to the end of the right track to the left track.

[0042] In summary, the automatic calibration fixture for magnetron anode antennas of this application can perform automated, assembly-line calibration of assembled magnetron anode assemblies without any discriminatory differences. Regardless of whether the anode assembly is qualified or the antenna is tilted before calibration, the anode assembly will definitely be qualified after calibration, and the antenna will definitely be perpendicular to the upper surface of the anode shell. Compared with traditional manual quality inspection and calibration, the automatic calibration fixture of this invention not only significantly improves the calibration speed and efficiency, but also avoids missed inspections and has good calibration quality, effectively improving the production efficiency and yield of anode assemblies. Furthermore, the production efficiency and yield of subsequent chips and magnetrons are also further improved. Attached Figure Description

[0065] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] An automatic calibration fixture for a magnetron anode antenna is provided for calibrating the antenna of the anode assembly of a magnetron, such as... Figure 9 As shown, the anode assembly 4 of the magnetron includes an anode housing 41, an antenna 42 and a center pin 44, with the upper end of the antenna 42 forming a flat end 43.

[0067] The clearly defined automatic calibration fixture includes a worktable 1 and a track 2 horizontally mounted on the worktable 1. A sliding mold base 3 is mounted on the track 2, and the sliding mold base 3 can slide horizontally along the track 2. The anode assembly 4 is mounted on the sliding mold base 3. Figure 3 As shown, the sliding mold base 3 includes a mounting plate 31 and a plurality of tube seats 32 arranged in a straight line on the mounting plate 31. The mounting plate 31 slides on the track 2 along the length of the track 2. The anode assembly 4 is detachably mounted on the tube seat 32. Specifically, the anode shell 41 of the anode assembly 4 is inserted into the tube seat 32.

[0068] like Figure 1 As shown, the workbench 1 is equipped with a first calibration device 8 and a second calibration device 9 for calibrating the antenna 42. The first calibration device 8 calibrates the antenna 42 from the left and right direction, and the second calibration device 9 calibrates the antenna 42 from the front and back direction. When the sliding mold base 3 moves along the track 2 to the calibration position of the first calibration device 8, it pauses its movement. After the antenna 42 is calibrated by the first calibration device 8, the sliding mold base 3 continues to move along the track 2 to the calibration position of the second calibration device 9 and pauses its movement to receive calibration from the second calibration device 9.

[0069] In operation, the automatic calibration fixture for the magnetron anode antenna of this device features a sliding mold base 3 that slides horizontally along the track 2, passing sequentially through the first calibration device 8 and the second calibration device 9. This means that the first and second calibration devices 8 and 9 clamp and calibrate the antenna 42 of the anode assembly 4 from the left-right and front-back directions. After two calibrations, the antenna 42 of the anode assembly 4 is calibrated to be qualified and no longer tilted. Therefore, regardless of whether the anode assembly 4 was qualified or not before calibration, or whether the antenna 42 was tilted, the anode assembly 4 will definitely be qualified after two calibrations, and the antenna 42 will definitely return to a vertical position perpendicular to the upper surface of the anode shell. Furthermore, since these two calibrations are performed gradually in an assembly line manner, the calibration speed and efficiency are significantly improved compared to existing manual quality inspection calibrations. Moreover, there are no missed inspections, resulting in high calibration quality and effectively improving the production efficiency and yield of the anode. Furthermore, the production efficiency and yield of subsequent cores and magnetrons are also further improved.

[0070] In this embodiment, the workbench 1 is further provided with a pinning device 10, a fourth calibration device 12, and a second transfer device 11; the sliding mold base 3 moves from the calibration position of the second calibration device 9 along the track 2 to the pinning position of the pinning device 10 and then stops moving. Then, the pinning device 10 knocks off the center pin 44 of the anode assembly 4 at the pinning position; the second transfer device 11 is used to transfer the anode assembly 4 after the pinning treatment by the pinning device 10 to the fourth calibration device 12, and to transfer the anode assembly 4 after calibration by the fourth calibration device 12 to the sliding mold base 3, and the sliding mold base 3 takes away the calibrated anode assembly 4; the fourth calibration device 12 is used to calibrate the antenna 42.

[0071] Because during the assembly of the anode assembly 4, the anode plate needs to be fixed relative to the anode housing 41 by the center pin 44. After the anode plate is welded, the center pin 44 needs to be removed. Therefore, the anode assembly 4, after being corrected by the first correction device 8 and the second correction device 9, needs to be de-pinned to remove the center pin 44. However, the de-pinning process may cause the antenna 42 to tilt again. Therefore, in order to avoid the antenna 42 tilting again during the de-pinning process of the corrected anode assembly 4, this embodiment adds a de-pinning device 10 and a fourth correction device 12 after the first correction device 8 and the second correction device 9. After the de-pinning device 10 completes the de-pinning operation, the fourth correction device 12 will correct the antenna 42 of the anode assembly 4 again to ensure that the antenna 42 is vertical and perpendicular to the upper surface of the anode housing 41. In this way, the automatic correction fixture provided in this embodiment also has a de-pinning function.

[0072] In this embodiment, as Figure 4 As shown, the first calibration device 8 includes a first mounting frame 81, at least one pair of first clamping plates 83, and a first linear actuator 82 horizontally mounted on the first mounting frame 81. The first mounting frame 81 is mounted on the workbench 1. When there are multiple pairs of first clamping plates 83, the multiple pairs of first clamping plates 83 are arranged in a straight line along the moving direction of the sliding mold base 3. The track 2 is located directly below at least one pair of first clamping plates 83. When the sliding mold base 3 moves along the track 2 into the calibration position within the first calibration device 8, the antenna 42 of the anode assembly 4 on the tube seat 32 can extend between a pair of first clamping plates 83. Therefore, when the antenna 42 extends into the area between a pair of first clamping plates 83, the movement of the sliding mold base 3 is immediately paused. Then, under the drive of the first linear actuator 82, the pair of first clamping plates 83 move closer to each other in the left and right direction to clamp the antenna 42. After clamping and calibration for a period of time, the pair of first clamping plates 83 move away from each other under the drive of the first linear actuator 82 to release the clamping of the antenna 42. At this time, the sliding mold base 3 can continue to move away from the calibration position of the first calibration device 8.

[0073] In this embodiment, the number of the first clamping plates 83 is twice the number of tube seats 32 on the mounting plate 31. For example, when there is only one tube seat 32 on the mounting plate 31, the first correction device 8 has only one pair of first clamping plates 83. When there are six tube seats 32 on the mounting plate 31 (e.g.) Figure 3 As shown), the first correction device 8 has 6 pairs of 12 first clamping plates 83 (as shown). Figure 4 As shown), each pair of first clamping plates 83 is used to clamp the antenna 42 of the anode assembly 4 on a tube seat 32. Under the drive of the first linear actuator 82, the six pairs of first clamping plates 83 synchronously move closer to each other to clamp the antenna 42 of the anode assembly 4 on the six tube seats 32 or move away from each other to loosen the clamping of the antenna 42.

[0074] In this embodiment, as Figure 4 As shown, the second correction device 9 includes a second linear actuator 91, at least one second linear actuator 93, and at least a pair of second clamping plates 94. The second linear actuator 91 is vertically mounted on the worktable 1 and connected to the second linear actuator 93, used to drive the second linear actuator 93 to move up and down. Each second linear actuator 93 is equipped with a pair of second clamping plates 94, which move closer to or further away from each other in the front-back direction. Figure 4 As shown, when the sliding mold base 3 moves along the track 2, it can pass directly under the second clamping plate 94. Therefore, when the sliding mold base 3 moves from the correction position of the first correction device 8 to the correction position of the second correction device 9 along the track 2, the antenna 42 of one anode component 4 on the sliding mold base 3 just moves to directly under the area between the pair of second clamping plates 94. At this time, the sliding mold base 3 can be controlled to pause its movement. Then, the second linear actuator 1 91 is controlled to drive the second linear actuator 2 93 and the second clamping plate 94 to descend until the antenna 42 extends between the pair of second clamping plates 94. Then, the second linear actuator 2 93 is controlled to drive the pair of second clamping plates 94 to move closer to each other and clamp the antenna 42 from the front and back direction. After clamping and correcting for a period of time, the second linear actuator 2 93 drives the pair of second clamping plates 94 to move away from each other and release the clamping of the antenna 42. Then, the second linear actuator 1 91 is controlled to drive the second linear actuator 2 93 and the second clamping plate 94 to rise and reset. Then, the sliding mold base 3 can continue to move away from the correction position of the second correction device 9.

[0075] In this embodiment, the number of the second linear actuators 93 is equal to the number of tube seats 32 on the mounting plate 31, and the number of the second clamping plates 94 is twice the number of tube seats 32 on the mounting plate 31. For example, when there is only one tube seat 32 on the mounting plate 31, the second correction device 9 has only one second linear actuator 93 and a pair of second clamping plates 94. When there are six tube seats 32 on the mounting plate 31 (e.g....), the number of tube seats 32 is...). Figure 3 As shown), the second correction device 9 has six second linear actuators 93, each of which is equipped with a pair of second clamping plates 94, for a total of six pairs of second clamping plates 94 (as shown). Figure 4 As shown), each pair of second clamping plates 94 is used to clamp the antenna 42 of the anode assembly 4 on a tube seat 32. Under the drive of the second linear actuator 93, the six pairs of second clamping plates 94 synchronously move closer to each other to clamp the antenna 42 of the anode assembly 4 on the six tube seats 32 or move away from each other to loosen the clamping of the antenna 42.

[0076] Considering that the upper end of the antenna 42 is a flat end 43, in order to avoid damaging the flat end 43 when the second clamping plate 94 clamps the antenna 42, the second clamping plate 94 is provided with an antenna rod correction groove 95 to accommodate the rod of the antenna 42. The second clamping plate 94 only clamps and corrects the rod of the antenna 42, and does not clamp the flat end 43 of the antenna 42.

[0077] In this embodiment, furthermore, to facilitate the fixed connection between the multiple second linear actuators 93 and the first linear actuator 91, such as... Figure 4 As shown, multiple second linear actuators 93 are fixedly mounted on a second mounting plate 92, and the second mounting plate 92 is fixedly mounted on a second linear actuator 91.

[0078] In this embodiment, as Figure 5 As shown, the pin-removing device 10 includes a third linear actuator 102, a third mounting plate 104, and at least one pin 105. The third linear actuator 102 is vertically mounted on the workbench 1 and connected to the third mounting plate 104, used to drive the third mounting plate 104 to move up and down. The pin 105 is vertically fixed below the third mounting plate 104 and can be driven by the third linear actuator 102 to press down and remove the center pin 44 of the anode assembly 4. Figure 5 As shown, when the sliding mold base 3 moves along the track 2, it can pass directly under the pinning post 105. Therefore, when the sliding mold base 3 moves from the correction position of the second correction device 9 along the track 2 to the pinning position of the pinning device 10, the anode housing 41 of an anode assembly 4 on the sliding mold base 3 just moves directly under the pinning post 105. At this time, the sliding mold base 3 can be controlled to pause its movement. Then, the third linear actuator 102 is controlled to drive the pinning post 105 to move downward and press down on the center pin 44, thereby knocking off the center pin 44. Then, the third linear actuator 102 is controlled to drive the pinning post 105 to move upward and reset. Then, the sliding mold base 3 can continue to move away from the pinning position of the pinning device 10.

[0079] In this embodiment, furthermore, to facilitate the installation and fixing of the third linear actuator 102 and its connection with the third mounting plate 104, such as... Figure 5As shown, a column 101 is vertically fixed on the workbench 1, a third linear actuator 102 is installed on the upper end of the column 101, a slide plate 103 is slidably installed on the column 101, the third linear actuator 102 is connected to the slide plate 103 and is used to push the slide plate 103 to move up and down along the column 101, and a third mounting plate 104 is fixedly connected to the slide plate 103.

[0080] In this embodiment, the structure of the dowel piling 105 is as follows: Figure 6 As shown, it has a slot with a straight cross-section, in which the antenna 42 can be accommodated. Therefore, the pin 105 can push down and knock off the center pin 44 of the anode assembly 4 after passing through the antenna 42, without damaging the antenna 42.

[0081] In this embodiment, the number of the pinning stakes 105 is equal to the number of anode components 4 on the sliding mold base 3, and when the sliding mold base 3 moves to the pinning position of the pinning device 10, there is a pinning stake 105 directly above each anode component 4.

[0082] In this embodiment, as Figure 1 and Figure 7 As shown, the fourth calibration device 12 includes a fourth mounting bracket 121, a fourth linear actuator 122, a lifting mold base 124, a lifting device 125, and at least one pair of fourth clamping plates 123. The fourth mounting bracket 121 is mounted on the workbench 1. The fourth linear actuator 122 is horizontally mounted on the fourth mounting bracket 121. The fourth clamping plates 123 are mounted on the fourth linear actuator 122. The fourth linear actuator 122 drives the pair of fourth clamping plates 123 to move closer to each other in the left-right direction to clamp the antenna 42 or to move away from each other to loosen the clamping of the antenna 42. The lifting device 125 is fixedly mounted on the workbench 1. The lifting mold base 124 is located below the fourth clamping plates 123 and is connected to the lifting device 125. The lifting device 125 pushes the lifting mold base 124 to move up and down. Figure 7 As shown, the structure of the lifting mold base 124 is the same as that of the sliding mold base 3. The difference is that the sliding mold base 3 can slide on the track 2, while the lifting mold base 124 can only be pushed up and down by the lifting device 125. In addition, the sliding mold base 3 can be equipped with multiple anode components 4, while the lifting mold base 124 can only be equipped with one anode component 4. Therefore, the fourth correction device 12 also needs to be equipped with multiple lifting devices 125 and multiple fourth linear actuators 122. The multiple fourth linear actuators 122 are all horizontally installed on the fourth mounting frame 121. Each lifting device 125 lifts one lifting mold base 124. The number of lifting mold bases 124 is equal to the number of fourth linear actuators 122. Each fourth linear actuator 122 is equipped with a pair of fourth clamping plates 123.

[0083] Furthermore, such as Figure 7 As shown, the anode assembly 4 on the lifting mold 124 is located directly below the area between a pair of fourth clamping plates 123. In this way, when the lifting device 125 pushes the lifting mold 124 up, the antenna 42 of the anode assembly 4 can extend from bottom to top into the area between the pair of fourth clamping plates 123. Then, the fourth linear actuator 122 is controlled to move the pair of fourth clamping plates 123 closer to each other in the left and right direction to clamp the antenna 42. After clamping and calibrating for a period of time, the fourth linear actuator 122 is controlled to move the pair of fourth clamping plates 123 further apart in the left and right direction to loosen the clamping of the antenna 42. Then, the lifting device 125 is controlled to move the lifting mold 124 down to reset.

[0084] In this embodiment, to better clamp and correct the antenna 42, the fourth clamping plate 123 is further provided with an antenna flat end correction groove 126 for accommodating the flat end 43 of the antenna 42, such as... Figure 7 As shown.

[0085] In this embodiment, as Figure 1 and Figure 5As shown, the transfer device 2 11 includes at least two fifth clamping plates 116, a fifth linear actuator 4 115, a fifth linear actuator 3 113, a fifth linear actuator 2 112, and a fifth linear actuator 111. The fifth linear actuator 111 is fixedly mounted on the worktable 1 via a fifth mounting bracket 117 and is at a certain height from the worktable 1. It is used to drive the fifth linear actuators 2 112, 3 113, 4 115, and the fifth clamping plates 116. 6. The anode assembly 4, clamped between a pair of fifth clamping plates 116, moves back and forth, transferring the anode assembly 4 from the sliding mold base 3 to the lifting mold base 124 of the fourth calibration device 12, and removing the anode assembly 4 from the lifting mold base 124 of the fourth calibration device 12 and transferring it to the sliding mold base 3. Then, the sliding mold base 3 slides along the track 2 to send away the calibrated anode assembly 4. The fifth linear actuator 2 112 is installed on the fifth linear actuator 1 111 and is used to drive the fifth linear actuator 3 11. 3. The fifth linear actuator 115, the fifth clamping plate 116, and the anode assembly 4 clamped between the pair of fifth clamping plates 116 move left and right, causing the anode assembly 4 to leave the sliding mold base 3 and be placed on the lifting mold base 124. The fifth linear actuator 113 is mounted on the fifth linear actuator 112 and is used to drive the fifth linear actuator 115, the fifth clamping plate 116, and the anode assembly 4 clamped between the pair of fifth clamping plates 116 to move up and down, causing the anode assembly 4 to leave the sliding mold base 3 and be placed on the lifting mold base 124. The fifth linear actuator 115 is placed on the lifting mold base 124 and mounted on the fifth linear actuator 113. The number of fifth linear actuators 115 is equal to the number of anode assemblies 4 on the sliding mold base 3 and the multiple lifting mold bases 124. Each fifth linear actuator 115 is equipped with a pair of fifth clamping plates 116. The fifth linear actuator 115 controls the pair of clamping plates to move closer to each other in the front-back direction to clamp the anode housing 41 of the anode assembly 4 or to move away from each other to release the clamping of the anode housing 41.

[0086] In this embodiment, to facilitate the connection between multiple fifth linear actuators four 115 and fifth linear actuator three 113, further, as... Figure 5 As shown, multiple fifth linear actuators 115 are fixedly mounted on a fifth mounting plate 114, and the fifth mounting plate 114 is fixedly connected to the fifth linear actuators 113.

[0087] In this embodiment, after the sliding mold base 3 moves a certain distance away from the pinning device 10, it stops on the track 2. At this time, the anode assembly 4 on the sliding mold base 3 is located directly to the right front of the area between a pair of fifth clamping plates 116. Then, the fifth linear actuator 2 112 pushes the fifth clamping plates 116 to move to the right front. The pair of fifth clamping plates 116 gradually approach the anode assembly 4. Relatively speaking, the anode assembly 4 extends into the pair of fifth clamping plates 116 from right to left. Then, the fifth linear actuator 4 115 moves to drive the pair of fifth clamping plates 116 to slide... The anode assembly 4 is clamped on the moving mold base 3. Then, the fifth linear actuator 3 113 drives a pair of fifth clamping plates 116 to move upward, causing the anode assembly 4 to leave the tube seat 32. Next, the fifth linear actuator 111 drives the fifth clamping plates 116 to move backward until the anode assembly 4 clamped between the fifth clamping plates 116 moves to directly above the tube seat 32 on the lifting mold base 124. Then, the fifth linear actuator 3 113 drives the fifth clamping plates 116 to move downward until the anode assembly 4 is stably placed on the lifting mold base 124. On the tube seat 32, the fifth linear actuator 4 115 then moves the fifth clamping plate 116 to loosen its clamping on the anode assembly 4. Finally, the fifth linear actuator 2 112 moves the fifth clamping plate 116 to the left, and the anode assembly 4, which has been placed on the lifting mold base 124, is immediately corrected by the fourth correction device 12. After the correction is completed, the fifth linear actuator 2 112 moves the fifth clamping plate 116 to the right to re-clamp the corrected anode assembly 4. Then, the fifth linear actuator 3 113 moves the fifth clamping plate 116 upward. The anode assembly 4 is moved away from the lifting mold base 124. Finally, the fifth linear actuator 111 drives the fifth clamping plate 116 to continue moving backward until the anode assembly 4 is transferred to the track 2 behind the fourth correction device 12. Then, the fifth linear actuator 313 drives the anode assembly 4 to descend and place it on the sliding mold base 3. The anode assembly 4 is taken away. Then, the fifth linear actuator 111 drives the fifth clamping plate 116 to move forward and reset, waiting to transfer the next anode assembly 4 from the sliding mold base 3 that comes out of the pinning device 10.

[0088] In this embodiment, the track 2 behind the fourth correction device 12 is the rear track 24, such as... Figure 1 As shown.

[0089] In this embodiment, the anode assembly 4 to be calibrated is manually placed on the sliding mold base 3. The sliding mold base 3 then travels along the track 2 sequentially through the first calibration device 8, the second calibration device 9, the pinning device 10, and the fourth calibration device 12. To provide workers with a larger working area for placing the anode assembly 4 onto the sliding mold base 3, thereby improving calibration efficiency, as shown below... Figure 2 and Figure 8As shown, further, the track 2 includes a left track 22 and a right track 23 arranged in parallel, and the sliding mold base 3 slides in opposite directions on the left track 22 and the right track 23, as shown. Figure 1 As shown, both ends of the left track 22 and the right track 23 are equipped with transfer devices 5. The front transfer device 5 is used to transfer the sliding mold base 3 from the left track 22 to the right track 23, and the rear transfer device 5 is used to transfer the sliding mold base 3 from the right track 23 to the left track 22. In this way, the worker can work on the entire left track 22 to place the anode assembly 4 on the sliding mold base 3, and then the sliding mold base 3 on the left track 22 moves forward and is finally sent to the right track 23 by the front transfer device 5. The first correction device 8, the second correction device 9, the pinning device 10 and the fourth correction device 12 are all provided. The sliding mold base 3 is placed on the right track 23. It moves from front to back on the right track 23, passing through the first correction device 8, the second correction device 9, and the pinning device 10 in sequence. When the sliding mold base 3 reaches the rear end of the right track 23, the second transfer device 11 removes the anode component 4 from the sliding mold base 3 and transfers it to the fourth correction device 12. After correction, it is transferred to the rear track 24 and taken away. The sliding mold base 3 at the rear end of the right track 23 is pushed to the rear end of the left track 22 by the rear transfer device 5. Then the sliding mold base 3 moves from back to front on the left track 22 and the worker places the anode component 4 on the tube seat 32 again.

[0090] In this embodiment, the structure of the transfer device 5 is as follows: Figure 2 As shown, it consists of a thrust mechanism 52 and a push plate 51. The thrust mechanism 52 pushes the push plate 51 to push the mounting plate 31 from the left track 22 to the right track 23 or from the right track 23 to the left track 22.

[0091] In this embodiment, the sliding of the sliding mold base 3 on the track 2 is achieved by a linear drive device 7, such as... Figure 2 and Figure 8 As shown, the track 2 consists of two straight rods 21 arranged parallel to each other on the worktable 1. The mounting plate 31 can slide along the length of the straight rods 21 in the area between the two straight rods 21. The worktable 1 between the two straight rods 21 is provided with a groove 6 parallel to the straight rods 21. The linear drive device 7 includes a slider 72 and a translation device 71 mounted on the lower surface of the worktable 1. The slider 72 is located in the groove 6, and the lower end of the slider 72 is connected to the translation device 71. The translation device 71 drives the slider 72 to slide horizontally along the groove 6. The sliding of the slider 72 drives the mounting plate 31 to move synchronously, thereby realizing the movement of the sliding mold base 3 on the track 2. For example, the upper surface of the slider 72 extends out of the groove 6. This movement of the slider 72 can push the mounting plate 31 in front of it to move. Of course, in other embodiments, the slider 72 can also be an electromagnet. By attracting the mounting plate 31 with the electromagnet, synchronous movement can also be achieved.

[0092] In this embodiment, the thrust mechanism 52, translation device 71, first linear actuator 82, second linear actuator 1 91, second linear actuator 2 93, third linear actuator 102, fifth linear actuator 1 111, fifth linear actuator 2 112, fifth linear actuator 3 113, fifth linear actuator 4 115, fourth linear actuator 122, and lifting device 125 can each be individually made of any form such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder, with a pneumatic cylinder being preferred.
