Description

Technical Field

[0001] The present application relates to the technical field of chip placement machine production equipment, and in particular to a method for controlling a cover plate of a chip placement machine. Background Art

[0002] In the existing integrated and automated mounting process, multiple objects are processed at the same time at one process point. In the existing solution, each tray is cooperated with a cover plate to realize the positioning and shaping of multiple flash light harness sub-modules. The cover plate is usually fixed on the tray with a magnet magnetic attraction structure. The weight and magnetic attraction of the cover plate itself are pressed on each flash light harness sub-module.

[0003] In order to generate sufficient positioning and shaping pressure for each flash light harness submodule, the cover plate weight and / or magnetic attraction force need to have certain strength requirements. If the cover plate weight or magnetic attraction force is insufficient, slight displacement is likely to occur at a high speed during the material tray transmission process and affect the overall shape of the multiple flash light lines below it. However, if the cover plate weight is heavy or the magnetic attraction force is large, it will cause difficulty in removing the cover plate before the mounting process. This contradiction seriously limits the stable and efficient operation of the flash light harness mounting process.

[0004] Finding a suitable method for controlling the cover of a patch device is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] Based on this, the present application proposes a cover control device for patch equipment to solve the problems in the prior art.

[0006] In one implementation, a method for controlling a cover plate of a patch device is provided, comprising the following steps:

[0007] After obtaining the arrival signal of the tray module at the cover plate removal station through the sensor, the tray of the tray module is fixed;

[0008] The cover plate adsorbent is driven to move at least two suction cups to above the cover plate removal station;

[0009] The suction cup of the cover plate adsorbent is driven to move downward and adsorb onto the upper surface of the cover plate;

[0010] The cover is separated from the pallet by the suction cup and moved away from the cover removal station.

[0011] In one implementation, the step of obtaining, by means of a sensor, a signal indicating that the tray module has reached the cover plate removal station includes:

[0012] A positioning hole is provided on the tray module, and the positioning hole can be provided on the tray or the cover plate;

[0013] When the tray module reaches the cover removal station, the detection light emitted by the light source of the displacement sensor passes through the positioning hole and is captured by the light receiver. When the light receiver continuously captures the detection light for more than a preset time threshold, it is determined that the tray module is located at the cover removal station.

[0014] In one implementation, the step of driving the cover plate adsorbent to move at least two suction cups to above the cover plate removal station includes:

[0015] The cover plate adsorbing body is lifted to the highest position by a vertical driving device so as to cross the transmission track;

[0016] The cover plate adsorption body is moved to above the cover plate removal station by a linear drive device.

[0017] In one implementation, the step of driving the suction cup of the cover plate adsorbent to move downward and adsorb on the upper surface of the cover plate includes:

[0018] The cover plate adsorbent is pressed down by a vertical driving device so that the suction cup is adsorbed on the upper surface of the cover plate.

[0019] In one implementation, the suction cup is connected to a vacuum pump via an air duct, and when the suction cup is adsorbed onto the upper surface of the cover plate, the vacuum pump is started to further adsorb and fix the suction cup onto the upper surface of the cover plate.

[0020] In one implementation, the step of separating the cover plate from the tray by using the suction cup includes:

[0021] The lifting device is started, the lifting rod is moved upward and the cover is lifted up, the lifted cover is further combined with the suction cup and firmly adsorbed, and the cover is separated from the pallet through the suction cup.

[0022] In one implementation, the step of moving the push rod upward and lifting the cover plate includes:

[0023] The tray is provided with an avoidance hole or an extension edge, and the push rod moves upward and passes through the avoidance hole to lift the cover plate, or the push rod moves upward and presses against the extension edge to lift the cover plate.

[0024] In one of the implementations, an electromagnet adsorption structure is provided between the tray and the cover plate of the tray module, and a trigger switch of the electromagnet adsorption structure is provided in the avoidance hole. When the push rod moves upward, it passes through the avoidance hole and turns off the adsorption force of the electromagnet adsorption structure through the trigger switch. The push rod continues to move upward to lift the cover plate to prevent the cover plate from being deformed or damaged.

[0025] In one implementation, after the ejector pin lifts the tray upward and fits it tightly against the suction cup, a vacuum pump connected to the suction cup through an air duct is started to fix the suction cup to the upper surface of the cover plate.

[0026] According to the patch equipment cover control method provided by the present application, compared with the prior art, the beneficial effects are: after obtaining the arrival signal of the tray module at the cover removal station through the sensor, the tray of the tray module is fixed; the cover adsorbent is driven to move at least two suction cups to the top of the cover removal station; the suction cups of the cover adsorbent are driven to move down and adsorb on the upper surface of the cover; the cover is separated from the tray and moved away from the cover removal station through the suction cup. Before the tray module reaches the cover removal station, the weight and magnetic attraction of the cover are not greatly restricted, and a larger weight and magnetic attraction can be set to ensure stability. Before the tray module reaches the cover removal station, the cover is moved away by the cover adsorbent, which improves the overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0033] In the existing integrated and automated mounting process, multiple objects are processed at the same time at one process point. In the existing solution, each tray is cooperated with a cover plate to realize the positioning and shaping of multiple flash light harness sub-modules. The cover plate is usually fixed on the tray with a magnet magnetic attraction structure. The weight and magnetic attraction of the cover plate itself are pressed on each flash light harness sub-module.

[0034] In order to generate sufficient positioning and shaping pressure for each flash light harness submodule, the cover plate weight and / or magnetic attraction force need to have certain strength requirements. If the cover plate weight or magnetic attraction force is insufficient, slight displacement is likely to occur at a high speed during the material tray transmission process and affect the overall shape of the multiple flash light lines below it. However, if the cover plate weight is heavy or the magnetic attraction force is large, it will cause difficulty in removing the cover plate before the mounting process. This contradiction seriously limits the stable and efficient operation of the flash light harness mounting process.

[0035] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, a method for controlling a patch device cover 10 is provided, comprising the following steps:

[0036] After obtaining the arrival signal of the tray 20 module at the cover plate 10 removal station 1 through the sensor, the tray 20 of the tray 20 module is fixed;

[0037] The cover plate 10 adsorbent is driven to move at least two suction cups to above the cover plate 10 removal station 1;

[0038] The suction cup of the cover plate 10 adsorbent is driven to move downward and adsorb onto the upper surface of the cover plate 10;

[0039] The cover plate 10 is separated from the tray 20 by the suction cup and removed from the cover plate 10 removal station 1 .

[0040] It should be noted that a sensor is provided to monitor whether the tray 20 module has arrived at the designated cover plate 10 removal station 1. When the tray 20 module arrives, the sensor sends an arrival signal. The sensor may be a photoelectric sensor or a proximity sensor. The sensor detects the presence of the tray 20 module. Once the arrival of the tray 20 module is detected, the control system receives a new signal and triggers an action to fix the tray 20 module to prevent movement or shaking in subsequent operations; activates the driving mechanism of the cover plate 10 adsorbent to move at least two (or more, determined according to the size and weight of the cover plate 10) suction cups to the top of the cover plate 10 removal station 1, ensuring that the suction cups can accurately align with the surface of the cover plate 10 to prepare for subsequent adsorption operations.

[0041] The control method of the patch equipment cover 10 provided in the present application provides an efficient and accurate way to handle the removal process of the cover 10 in the automated placement process, and achieves accurate control and rapid removal of the cover 10 by integrating sensors, mechanical drives and adsorption technologies.

[0042] According to the control method of the patch equipment cover 10 provided by the present application, compared with the prior art, the beneficial effects are: after obtaining the arrival signal of the tray 20 module at the cover 10 removal station 1 through the sensor, the tray 20 of the tray 20 module is fixed; the cover 10 adsorbent is driven to move at least two suction cups to the top of the cover 10 removal station 1; the suction cups of the cover 10 adsorbent are driven to move downward and adsorb on the upper surface of the cover 10; the cover 10 is separated from the tray 20 and removed from the cover 10 removal station 1 through the suction cups. Before the tray 20 module arrives at the cover 10 removal station 1, the weight and magnetic attraction of the cover 10 are not greatly restricted, and a larger weight and magnetic attraction can be set to ensure stability. Before the tray 20 module arrives at the cover 10 removal station 1, the cover 10 is removed by the cover 10 adsorbent, which improves the overall stability.

[0043] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, the step of obtaining a signal indicating that the tray 20 module has reached the cover plate 10 removal station 1 through a sensor includes:

[0044] A positioning hole is provided on the tray 20 module, and the positioning hole can be provided on the tray 20 or the cover plate 10;

[0045] When the tray 20 module arrives at the cover plate 10 removal station 1, the detection light emitted by the light source of the displacement sensor passes through the positioning hole and is captured by the light receiver. When the light receiver continuously captures the detection light for a time period exceeding a preset time threshold, it is determined that the tray 20 module is located at the cover plate 10 removal station 1.

[0046] It should be noted that a positioning hole is pre-set on the tray 20 module or the cover plate 10, and the position and size of the positioning hole need to be set according to the specific structure of the tray 20 module or the cover plate 10 to ensure that the sensor is accurately positioned through the positioning hole. In addition, the detection time is obtained by the light receiver. When it exceeds the preset time threshold, it is judged that the tray 20 module is located at the cover plate 10 removal station 1. If it does not reach the preset time threshold, it is judged that the tray 20 module is not accurately stopped at the cover plate 10 removal station 1.

[0047] See also Figure 1 , Figure 2 , Figure 3As shown, in one embodiment, the step of driving the cover plate 10 adsorbent to move at least two suction cups to above the cover plate 10 removal station 1 includes:

[0048] The cover plate 10 adsorbent is lifted to the highest position by the vertical driving device 40 to cross the transmission track;

[0049] The cover plate 10 adsorption body is moved to above the cover plate 10 removal station 1 by the linear drive device 50 .

[0050] It should be noted that the cover plate 10 adsorbent is lifted to the highest position as a whole by the vertical drive device 40, which can be one of a cylinder, a servo motor with a lead screw, a lifting mechanism, and the like. After the cover plate 10 adsorbent is lifted to the highest position and crosses the transmission track, it is horizontally displaced to the top of the cover plate 10 removal station 1 by the linear drive device 50, which can be a linear guide rail, a servo motor with a slider, and the like. This step is the key to achieving precise positioning, because the linear drive device 50 can provide a stable and precise motion trajectory. During the displacement process, it is necessary to monitor the position of the cover plate 10 adsorbent in real time and adjust it according to the preset coordinate parameters to ensure that it can accurately stay directly above the cover plate 10 removal station 1.

[0051] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, the step of driving the suction cup of the cover plate 10 adsorbent to move downward and adsorb on the upper surface of the cover plate 10 includes:

[0052] The cover plate 10 adsorbent is pressed down by the vertical driving device 40 so that the suction cup is adsorbed on the upper surface of the cover plate 10 .

[0053] It should be noted that, further, a detection device may be provided to detect the adsorption state. In order to ensure that the suction cup has been successfully adsorbed on the cover plate 10, the adsorption state may be monitored by a sensor or other detection device. For example, it may be detected whether the negative pressure value inside the suction cup has reached a preset threshold, or the contact between the suction cup and the cover plate 10 may be observed by a visual system.

[0054] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, the suction cup is connected to a vacuum pump through an air duct. When the suction cup is adsorbed onto the upper surface of the cover plate 10 , the vacuum pump is started to further adsorb and fix the suction cup onto the upper surface of the cover plate 10 .

[0055] It should be noted that the suction cup is connected to the vacuum pump through an air duct, and the vacuum pump is started after the suction cup is initially adsorbed onto the cover plate 10 to further enhance the adsorption force, which can ensure that there is sufficient adsorption force to absorb the suction cup and facilitate the removal of the cover plate 10.

[0056] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, the step of separating the cover plate 10 from the tray 20 by the suction cup includes:

[0057] The lifting device is started to move the lifting rod 70 upward to lift the cover plate 10, and the lifted cover plate 10 is further combined with the suction cup and firmly adsorbed, and the cover plate 10 is separated from the tray 20 by the suction cup.

[0058] It should be noted that the cover plate 10 is lifted up by the lifting device, and the cover plate 10 is separated from the tray 20 by the suction cup, and the lift rod 70 moves upward in the vertical direction, gradually approaching and contacting the lower surface of the cover plate 10. In the process of the cover plate 10 being lifted up, since the suction cup has been firmly adsorbed on the upper surface of the cover plate 10, the combination between the cover plate 10 and the suction cup will become tighter, ensuring that the cover plate 10 can be stably maintained on the suction cup during the subsequent movement.

[0059] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, the step of moving the push rod 70 upward and lifting the cover plate 10 includes:

[0060] The tray 20 is provided with an avoidance hole or an extension edge, and the push rod 70 moves upward and passes through the avoidance hole to lift up the cover plate 10, or the push rod 70 moves upward and presses on the extension edge to lift up the cover plate 10.

[0061] It should be noted that, for the previous embodiment, when the control system issues an instruction, the lifting device starts to work, driving the lift rod 70 to move upward. The lift rod 70 rises vertically along a preset trajectory until it passes through the avoidance hole of the tray 20.

[0062] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, an electromagnet adsorption structure is provided between the tray 20 and the cover plate 10 of the tray 20 module, and a trigger switch of the electromagnet adsorption structure is provided in the avoidance hole. When the push rod 70 moves upward, it passes through the avoidance hole and turns off the adsorption force of the electromagnet adsorption structure through the trigger switch. The push rod 70 continues to move upward to lift the cover plate 10 to prevent the cover plate 10 from being deformed or damaged.

[0063] It should be noted that when the control system issues an instruction, the lifting device starts to work and drives the lift rod 70 to move upward; the lift rod 70 rises vertically along the preset trajectory until it passes through the avoidance hole of the tray 20; in the process of passing through the avoidance hole, the lift rod 70 contacts the trigger switch and triggers it; the trigger switch then sends a signal to the control system, and the control system responds to this signal and cuts off the power supply of the electromagnet; as the power supply of the electromagnet is cut off, the adsorption force generated by it disappears rapidly. At this time, the cover plate 10 is no longer affected by the adsorption force from the electromagnet; because the adsorption force of the electromagnet has been turned off before the lift rod 70 lifts the cover plate 10, the cover plate 10 will not be subjected to sudden pulling force or pressure from the electromagnet during the separation process, thereby avoiding possible deformation or damage.

[0064] See also Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, after the push rod 70 lifts the tray 20 upward and fits it tightly with the suction cup, the vacuum pump connected to the suction cup through the air duct is started to fix the suction cup to the upper surface of the cover plate 10.

[0065] It should be noted that before the top rod 70 tightly fits the tray 20 and the suction cup, the suction cup has been connected to the vacuum pump through the air duct. This connection ensures that when the vacuum pump is started, negative pressure can be quickly generated inside the suction cup; as the negative pressure is generated, the air between the suction cup and the upper surface of the cover plate 10 is quickly discharged, forming a relatively vacuum environment. The adsorption force generated by this negative pressure environment firmly adsorbs the suction cup on the cover plate 10; since the tray 20 is tightly fitted with the suction cup at this time, this adsorption force also indirectly acts on the tray 20, further enhancing the overall stability.

[0066] It should be noted that when an element is referred to as being "fixed on" or "set on" another component, it can be directly on the other component or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.
