Description

Technical Field

[0001] The utility model relates to the technical field of piano shaft frame linkage assembly, in particular to a dotting mechanism for sensor production. Background Art

[0002] The Hall sensor is a magnetic field sensor made based on the Hall effect. It can detect and isolate the primary current from the test circuit, and has the advantages of wide measurement range, high accuracy, good linearity, short response time, etc. When current passes through a wire, a magnetic field will be generated around the wire, and the magnitude of the magnetic field is proportional to the current passing through the wire. This magnetic field can be gathered by soft magnetic materials. The magnetic core of the Hall current sensor is a magnetic core with an air gap made of soft magnetic materials. Commonly used soft magnetic materials include silicon steel sheets, Permalloy, nanocrystalline magnetic cores, etc. The Hall effect is a type of magnetoelectric effect, which is widely used in industrial automation technology, detection technology, and information processing.

[0003] During the production of Hall sensors, the program needs to be burned into the sensor. The traditional sensor production and burning process is generally that the staff first loads the sensor, puts it into the burning fixture, and then burns it through the burning mechanism. After the burning is completed, the staff marks the burned good products. Generally, ink is used to dot the sensor for subsequent identification, and then observe whether the dotting is successful. Due to the small size of the sensor and the large amount of burning required, manual dotting requires the use of a dotting tool for dotting each time, and each dotting requires dipping in ink. The dotting efficiency is not high, and it is easy to have inaccurate dotting, resulting in wrong dotting or missing dotting, which affects subsequent production.

As for the principle of fine-tuning, it is the existing technology and will not be elaborated here. Fine-tuning of multiple degrees of freedom can be achieved.

[0027] Please refer to Figure 1-5 The dotting mechanism includes a second mounting plate 106 fixed on the side of the third fine-tuning displacement platform 105 away from the first mounting plate 104, a lifting drive cylinder 107 is installed on the top of the second mounting plate 106 away from the third fine-tuning displacement platform 105, a connecting block 108 is fixed to the output end of the lifting drive cylinder 107, guide plates 109 are fixed on both sides of the connecting block 108, a guide plate 2 110 is provided on the side where the two guide plates 109 are close to each other, the guide plate 2 110 is fixedly connected to the second mounting plate 106, and a dotting assembly is provided between the two guide plates 110. Specifically, when dotting work is required, the lifting drive cylinder 107 is started to drive the connecting block 108 to perform a lifting movement, and then drive the guide plate 109 to perform a lifting movement, and the lifting movement of the guide plate 109 drives the dotting assembly to press down to dot the sensor or flip the sensor up to dip ink.

[0028] Please refer to Figure 1-5The dotting assembly includes a dotting block 114, a mounting cavity 124 is provided on the inner side of the bottom of the dotting block 114, a protective collar 119 is slidably connected to the inner side of the mounting cavity 124, a dotting head 120 is slidably connected to the inner side of the protective collar 119, a connecting plate 123 is fixed to the bottom of the dotting head 120 through the protective collar 119, a spring 125 is provided at the bottom of the connecting plate 123, and the two ends of the spring 125 are respectively connected to the dotting block 114 and the connecting plate 123, a second connecting column 118 is provided on both sides of the dotting block 114, and a second guide groove 117 is provided on both sides of the dotting block 114 and above the second connecting column 118.

Specifically, The dotting process is that the lifting drive cylinder 107 is started to drive the connecting block 108 and the guide plate 109 to move downward, and the dotting block 114 is driven to move downward as a whole through the guide plate 109, and the sensor is dotted by the contact between the dotting head 120 and the surface of the sensor. During the dotting process, in order to protect the sensor, the dotting head 120 first contacts the sensor. When the dotting head 120 contacts the sensor and the pressure on the sensor reaches a certain value, the spring 125 is deformed and compressed under the action of the dotting head 120, and the dotting head 120 dots the sensor and shrinks to the inside of the protective ring 119. When the dotting head 120 shrinks into the inside of the protective ring 119, the protective ring 119 is subjected to pressure and presses the connecting plate 123, and the spring 125 continues to shrink through the connecting plate 123, and the sensor is protected by the setting of the spring 125.

[0029] Please refer to Figure 1-5Fourth guide grooves 126 are provided on both sides of the inner part of the guide plate 109, and a third connecting column 121 adapted to the fourth guide groove 126 is provided on the second guide plate 110. The guide plate 109 is slidably connected to the second guide plate 110 through the cooperation between the third connecting column 121 and the corresponding fourth guide groove 126; a first guide groove 115 adapted to the second connecting column 118 is provided on the inner side of the second guide plate 110, and the second connecting column 118 passes through the first guide groove 115 located on the same side and is slidably connected to the second guide plate 110 located on the same side through the first guide groove 115; the bottom of the guide plate 109 A third guide groove 122 adapted to the second connecting column 118 is provided on the inner side of the second guide plate 110, and the second connecting column 118 passes through the third guide groove 122 located on the same side and is slidably connected to the guide plate 109 located on the same side through the third guide groove 122; a first connecting column 116 adapted to the second guide groove 117 is provided on the side of the guide plate 110 close to the dotting block 114, and the first connecting column 116 is inserted into the inner side of the second guide groove 117 on the same side and is slidably connected to the dotting block 114 through the second guide groove 117. An ink cartridge 117 is provided between the two guide plates 110 and above the dotting assembly. 1, the top of the ink cartridge 111 is detachably connected with a cover plate 112, the second guide plate 110 is provided with a support step 113 at the bottom of the ink cartridge 111 and close to one side of the ink cartridge 111, the ink cartridge 111 is slidably connected to the top of the support step 113, and the bottom of the ink cartridge 111 and above the dotting head 120 is provided with an ink outlet hole, specifically, each third connecting column 121 corresponds to a fourth guide groove 126, and the second guide plate 110 guides the movement of the first guide plate 109 through the cooperation of the third connecting column 121 and the fourth guide groove 126; the second guide plate 110 guides the movement of the first guide plate 109 through the first guide groove 115 The second connecting column 118 performs limiting and guiding, thereby limiting and guiding the movement of the dotting block 114. At the same time, the second guide plate 110 limits and guides the dotting block 114 through the cooperation between the first connecting column 116 and the second guide groove 117. Through the cooperation between the second guide groove 117 and the first connecting column 116, the dotting block 114 can rotate around the first connecting column 116 while sliding on the outside of the first connecting column 116. On the other hand, the first guide plate 109 limits the movement of the dotting block 114 through the cooperation between the third guide groove 122 and the second connecting column 118.

[0030] It should be noted that the third guide groove 122 limits the lateral movement of the second connecting column 118, and the first guide groove 115 is divided into three sections, namely, upper and lower vertical sections and an arc section in the middle. The center lines of the upper and lower vertical sections are located on the same vertical line, the arc section is opened at 180 degrees, and the central axis of the arc section is collinear with the central axis of the first connecting column 116. The first guide groove 115 guides the second connecting column 118 in the lateral direction through the vertical section, and guides the longitudinal movement through the curved section. The second guide groove 117 and the first connecting column 116 are set to limit the displacement of the dotting block 114 in the vertical direction.

[0031] On the other hand, by setting the ink cartridge 111, before use, ink is put into the ink cartridge 111, and the ink cartridge 111 is pushed into the inner side of the two guide plates 110, which is convenient for replacing ink. When it is necessary to dip ink, the dotting head 120 is moved to the ink outlet hole at the bottom of the ink cartridge 111, and the end of the dotting head 120 is extended into the ink outlet hole to dip ink.

[0032] In this embodiment, the dotting process is as follows: first, the sensor is transported to the bottom of the dotting head 120. In the initial position, the dotting head 120 faces upward and is located below the ink outlet at the bottom of the ink cartridge 111. Then, the lifting drive cylinder 107 is started to drive the connecting block 108 to move downward, and then drives the guide plate 109 to move downward. While the guide plate 109 moves downward, due to the limiting effect of the third guide groove 122 on the second connecting column 118, the guide plate 109 drives the dotting block 114 to move downward. Due to the three-stage design of the first guide groove 115, the movement of the dotting block 114 is divided into three parts. First, the dotting block 114 is driven downward by the guide plate 109. At this time, the dotting block 114 moves vertically downward. In this section of movement The first guide groove 115 limits and guides the movement of the dotting block 114 through the vertical section located above. When the second connecting column 118 moves to the inner side of the arc section, due to the limitation of the first connecting column 116, the dotting block 114 rotates around the first connecting column 116, and the rotation angle is 180 degrees, so that the dotting block 114 flips over. When the second connecting column 118 moves from the arc section to the inner side of the vertical section located below, the dotting head 120 faces downward. Subsequently, the dotting block 114 moves downward in the vertical section located below, driving the dotting head 120 to move downward. First, the dotting head 120 contacts the sensor and puts a dot on the sensor. After the dotting is completed, the lifting drive cylinder 107 starts again to drive the dotting block 114 to reset and dip in ink.

[0033] Please refer to Figure 1The visual inspection module 200 includes a second mounting frame 201 arranged on the side of the first mounting frame 101 close to the dotting block 114, and a detection camera 202 is installed on the second mounting frame 201. A light source 203 is installed on the second mounting frame 201 and located on the side of the detection camera 202 close to the first mounting frame 101. Specifically, the dotting effect is detected by setting the detection camera 202 to determine whether dots are applied.

[0034] The working principle of a dot-marking mechanism for sensor production provided by the utility model is:

[0035] When the present mechanism is used, the sensor is first transported to the bottom of the dotting head 120. In the initial position, the dotting head 120 faces upward and is located below the ink outlet hole at the bottom of the ink cartridge 111. Then, the lifting drive cylinder 107 is started to drive the connecting block 108 to move downward, thereby driving the guide plate 109 to move downward. While the guide plate 109 moves downward, due to the limiting effect of the third guide groove 122 on the second connecting column 118, the guide plate 109 drives the dotting block 114 to move downward. The three-stage design of 115 makes the movement of the dotting block 114 divided into three parts. First, the dotting block 114 is driven by the guide plate 109 to move downward. At this time, the dotting block 114 moves vertically downward. In this movement, the first guide groove 115 limits the movement of the dotting block 114 through the vertical section located above. When the second connecting column 118 moves to the inner side of the arc segment, due to the limitation of the first connecting column 116, the dotting block 114 rotates around the first connecting column 116, and the rotation angle is 18 0 degrees, so that the dotting block 114 flips over, when the second connecting column 118 moves from the arc section to the inner side of the vertical section below, the dotting head 120 faces downward, and then the dotting block 114 moves downward in the vertical section below, driving the dotting head 120 to move downward. First, the dotting head 120 contacts the sensor and puts a dot on the sensor. When the dotting head 120 contacts the sensor and the pressure on the sensor reaches a certain value, the spring 125 is deformed under the action of the dotting head 120. Compression, at this time, the dotting head 120 shrinks toward the inner side of the protective collar 119. When the dotting head 120 shrinks into the inner side of the protective collar 119, the protective collar 119 is subjected to pressure and presses the connecting plate 123, and the spring 125 continues to shrink through the connecting plate 123. The sensor is protected by the setting of the spring 125. After the dotting is completed, the lifting drive cylinder 107 is started again to drive the dotting block 114 to reset and dip in ink. At the same time, the visual inspection module 200 is started to inspect the dotting effect through the inspection camera 202;

[0036] When the ink needs to be replaced, the ink cartridge 111 only needs to be pulled out from the inner side of the guide plate 110 on both sides and the cover plate 112 is opened.
