[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] With the development of automation technology, a method for processing tin bars efficiently and accurately is needed, such as Figure 1 As shown, Figure 1 The schematic diagram of the process of an embodiment of the method for processing the tin stopper provided in the present application includes the following steps:

[0030] Step S11: Set the number of tin-blocking bars to be processed, the length of each section of the tin-blocking bar, and the number of holes in each section of the tin-blocking bar; each section of the tin-blocking bar includes at least a head hole and a tail hole; for example, the number of tin-blocking bars to be processed is 10, the length of each section of the tin-blocking bar is 100 mm, and the number of holes in each section of the tin-blocking bar is 2; in other embodiments, the relevant values ​​can be changed according to actual conditions and are not limited to this; by accurately setting the number, length and number of holes of each section of the tin-blocking bar, as well as the positions of the head hole and the tail hole, it can be ensured that each processing meets the user's needs; clear parameter settings can reduce processing errors caused by improper parameter settings and improve processing accuracy.

[0031] Step S12: The first hole distance is the length of the first hole from the side close to the tin stop bar, and the tail hole distance is the length of the tail hole from the other side of the tin stop bar; for example, the first hole is set on the left side of the tin stop bar, and the tail hole is set on the right side of the tin stop bar, the first hole distance is the length of the first hole from the left side of the tin stop bar, and the tail hole distance is the length of the tail hole from the right side of the tin stop bar; the first hole distance and the tail hole distance are the same; in one embodiment, the first hole distance and the tail hole distance are both 20mm, and the specific value is not limited here, as long as the first hole distance + tail hole distance < the length of the tin stop bar. Setting the first hole distance and the tail hole distance to be the same can ensure the symmetry of the tin stop bar and the uniform distribution of the holes.

[0032] Step S13: Set the running speeds of the feeding shaft, cutting shaft and punching shaft through the servo motor, and then control the feeding speed, cutting speed and punching speed; for example, set the feeding speed to 100mm / s, the cutting speed to 200mm / s, and the punching speed to 150mm / s; the feeding shaft moves along the first direction, and the cutting shaft and the punching shaft move along the second direction; the first direction is perpendicular to the second direction, for example, the first direction is the horizontal direction, and the second direction is the vertical direction.

[0033] Step S14: Set the flush return value and flush discharge length before processing the tin stop bar. Based on the flush return value, accurately align the tin stop bar to the next processing position to avoid processing errors caused by inaccurate position; calibrate the position of the tin stop bar based on the flush discharge length to ensure that the tin stop bar is in the correct initial position before processing; by reasonably setting the flush return value and flush discharge length, the processing quality and consistency of the tin stop bar can be significantly improved, the scrap rate caused by inaccurate position can be reduced, and the qualified rate of the product can be improved. The working process of the tin stop bar processing in this embodiment is described in detail below:

[0034] The feeding shaft keeps the feeding speed to horizontally transport the tin-blocking bar. When the displacement difference between the front end of the tin-blocking bar and the punching shaft in the horizontal direction reaches the first hole distance, the feeding shaft stops working.

[0035] The punching shaft maintains the punching speed and approaches the tin blocking bar in the vertical direction. After contacting the tin blocking bar, the first hole, i.e., the first hole, is punched. After the punching shaft completes the punching, the punching shaft is reset.

[0036] The feeding shaft continues to feed the material. When the displacement difference between the front end of the tin stop bar and the punching shaft in the horizontal direction reaches the preset length of the tin stop bar - the tail hole distance, the feeding shaft stops working.

[0037] The punching shaft punches the second hole, i.e. the tail hole. After the punching shaft completes the punching, the punching shaft is reset;

[0038] The feeding shaft continues to feed the material. When the displacement difference between the front end of the tin stop bar and the cutting shaft in the horizontal direction reaches the preset length of the tin stop bar, the feeding shaft stops working and the cutting shaft cuts the tin stop bar in the vertical direction to complete the tin stop bar processing.

[0039] In this embodiment, a section of the tin retaining bar is provided with only two holes. In other embodiments, a section of the tin retaining bar may be provided with three, four or five holes, without any limitation here. It should be clarified that in order to improve the processing accuracy, only one of the feeding axis, punching axis and cutting axis can be in working state at the same time period.

[0040] In summary, the tin stopper bar processing method of the present embodiment includes: setting the number of tin stopper bars to be processed, the length of each section of the tin stopper bar, and the number of holes of each section of the tin stopper bar; each section of the tin stopper bar includes at least a first hole and a tail hole; the first hole distance is the length of the first hole from the side close to the tin stopper bar, and the tail hole distance is the length of the tail hole from the other side of the tin stopper bar; the first hole distance is the same as the tail hole distance; the running speed of the feeding axis, the cutting axis and the punching axis is set by a servo motor, thereby controlling the feeding speed, the cutting speed and the punching speed; setting the flush back value and the flush discharge length before processing the tin stopper bars, accurately aligning the tin stopper bars based on the flush back value, and calibrating the position of the tin stopper bars based on the flush discharge length. Through the above method, the accuracy and efficiency of tin stopper bar processing are improved, material waste is reduced, and costs are reduced.

[0041] In one embodiment, the servo motor can also set a punching position offset value, which is the deviation between the actual punching position and the set position; due to mechanical errors, material properties and other factors, the actual punching position of the punching axis may deviate from the set position. For example, if the set first hole position is 20mm, but the actual punching position is 18.9mm, then the punching position offset should be set to 1.1mm; the punching position offset value is the deviation between the actual punching position and the set position. By setting the punching position offset value, this deviation can be compensated to ensure the accuracy of the punching position and improve the punching accuracy.

[0042] The photoelectric sensor obtains the position of the tin stop bar, and then obtains the actual punching position; the photoelectric sensor is used to obtain the position of the tin stop bar to ensure that the photoelectric sensor can accurately detect the actual position of the tin stop bar; according to the actual position feedback from the photoelectric sensor, the punching position offset value is adjusted to ensure that the actual punching position is consistent with the set position.

[0043] In one embodiment, the servo motor can also set the thickness of the cutting blade. Different cutting blades correspond to different cutting blade thicknesses. The accuracy of the length of the tin stop bar is improved based on the setting of the cutting blade thickness. The cutting blade thickness refers to the actual thickness of the cutting blade. When calculating the length of each section of the tin stop bar, the thickness of the cutting blade needs to be considered because a portion of the tin stop bar will be consumed during the cutting process. For example, the thickness of the cutting blade is 0.5 mm.

[0044] By setting the thickness of the cutting blade, you can ensure that the calculated length of each section of the tin stopper is more accurate. This can avoid the length error caused by cutting loss and improve cutting accuracy; accurate cutting blade thickness setting can reduce the length error caused by inaccurate thickness and ensure that the length of each section of the tin stopper meets the requirements.

[0045] In one embodiment, the cutting blade counts +1 after each cutting, and compares the total number of cuttings with the preset number of times of the cutting blade. If the total number of cuttings is not less than the preset number of times of the cutting blade, the cutting blade is replaced. The steps of replacing the cutting blade are described in detail below:

[0046] After each cutting, the cutting count will be automatically increased, and the control unit will record the total number of cuttings after each cutting;

[0047] The control unit will compare the total number of cuts with the preset number of times of the cutting disc; if the total number of cuts is less than the preset number of times of the cutting disc, it will work normally; if the total number of cuts is not less than the preset number of times of the cutting disc, the control system will issue an alarm or prompt to remind the operator to replace the cutting disc;

[0048] After replacing the cutting disc with a new one, reset the cutting count.

[0049] By setting the preset number of cutting discs and counting the cutting times, it can be ensured that the cutting discs are replaced in time after reaching the end of their service life, thus avoiding the reduction of processing accuracy due to wear of the cutting discs and improving processing efficiency. It should be clarified that cutting discs of different materials correspond to different preset numbers of cutting discs.

[0050] In one embodiment, the drill bit counts +1 after each hole is drilled, and the total number of holes drilled is compared with the preset number of times the drill bit is used. If the total number of holes drilled is not less than the preset number of times the drill bit is used, the drill bit is replaced. The steps for replacing the drill bit are the same as those for replacing the cutting blade, and are not repeated here. It should be noted that the preset numbers of the drill bit and the cutting blade may be the same or different, and replacing the drill bit and replacing the cutting blade are two independent steps. Only when the drill bit and the cutting blade can work normally can the tin retaining bar be processed normally.

[0051] In one embodiment, the control unit can obtain the feeding speed, cutting speed and punching speed, and compare them with the running speeds of the feeding axis, cutting axis and punching axis set by the servo motor respectively. If the actual error exceeds the preset error, an alarm is issued.

[0052] The preset error can be set freely, for example, the preset error is 5%; the control unit obtains the feeding speed, cutting speed and punching speed in real time; the control unit compares these actual speeds with the running speeds of the feeding axis, cutting axis and punching axis set by the servo motor; for example, the set feeding speed is 100mm / s, the actual speed is 106mm / s, and the error is Make an alarm.

[0053] Real-time monitoring and comparison can promptly detect speed deviations, ensure that the speed of each processing step meets the set value, and improve processing accuracy; timely detection and correction of speed errors can reduce processing errors caused by speed fluctuations and ensure the accuracy of each hole and cutting position.

[0054] In one embodiment, the tin stopper bar includes N holes, N ≥ 2; the distance between any two adjacent holes is like Figure 2 As shown, Figure 2This is a schematic diagram of the structure of an embodiment of the tin stop bar provided in the present application. The tin stop bar is 100 mm long, the distance between the first hole is 20 mm, and the distance between the last hole is also 20 mm. Four holes are punched; the distance between any two adjacent holes is The calculation method of the spacing distance between any two adjacent holes of the solder retaining bar of other embodiments will not be described in detail here.

[0055] Clear hole spacing can ensure that the position of each hole meets the design requirements and improve the punching accuracy; precise hole spacing can reduce errors caused by inaccurate positioning and ensure the uniform distribution of each hole; the spacing between any two adjacent holes in a section of tin stopper bar is the same, and the distance between the first hole and the distance between the last hole are equal, which improves the symmetry of the tin stopper bar.

[0056] The present application also provides a tin blocking bar processing device, such as Figure 3 As shown, Figure 3 The structural schematic diagram of an embodiment of the tin-blocking bar processing device provided in the present application includes:

[0059] The control unit is used to receive the set parameters and control the operation of the processing equipment. The control unit can also obtain the feeding speed, cutting speed and punching speed.

[0060] The alarm module is connected to the control unit and determines whether to alarm based on the output signal of the control unit.
