Description

TECHNICAL FIELD

[0001] The present application relates to the field of tape packaging equipment for small electronic components, in particular to a tape packaging equipment for small electronic components and a tape packaging method. BACKGROUND

[0002] The tape packaging equipment is to carry and store electronic components such as resistors, capacitors, transistors, diodes, ICs, etc. in the groove cavities of the carrier tape, and to form a closed packaging by sealing the cover film (upper tape) above the carrier tape, so as to protect the electronic components from being contaminated, damaged or irregularly scattered during transportation, and to ensure the automatic production and use in the terminal factory.

[0003] In order to prevent the delivery of defective products, an inspection link is provided on the tape packaging equipment, which can be implemented before the sealing treatment of the tape packaging or after the sealing treatment. For example, by inspecting before the sealing treatment, it can be judged whether the state of the electronic product and the carrier tape after the sealing treatment is normal. In addition, the inspection after the sealing treatment can judge whether the sealing treatment is normal (i.e. whether the electronic product is normally packaged by the carrier tape).

[0004] However, in the existing tape packaging equipment, the packaging treatment (especially the sealing treatment) and the inspection treatment are independent of each other and are carried out in a non-linked state. Therefore, the inspection treatment may not be carried out in the most appropriate conditions. For example, the inspection treatment is not linked with the sealing treatment, resulting in that the timing of the implementation of the inspection treatment and the sealing treatment of the tape packaging is not related, i.e. when the abnormality is detected, the whole machine cannot be marked or stopped in time. SUMMARY

[0005] The present application aims to provide a tape packaging equipment and a tape packaging method.

[0006] To achieve the above-mentioned purpose, the technical scheme of the equipment adopted by the present application is: a tape packaging equipment, characterized in that it comprises:

[0007] a sealing unit for heat-sealing the upper tape on the carrier tape on which the products are placed;

[0008] a first inspection unit for inspecting the heat-sealing state of the heat-sealed carrier tape and upper tape;

[0009] a control unit for controlling the sealing unit and the first inspection unit;

[0010] Among them, the control unit controls the action of the sealing unit, and then controls the first inspection unit to implement inspection based on the action signal of the sealing unit, and performs abnormality treatment if the inspection result is abnormal.

[0011] In the above solution, further, the control unit controls the conveying unit to intermittently convey and intermittently stop the carrier tape according to a set moving amount, and the first inspection unit completes the inspection during the intermittent stop of the carrier tape.

[0012] Still further, the solution further comprises a second inspection unit for inspecting the state of the workpiece on the carrier tape before heat sealing, and the control unit controls the second inspection unit to perform the inspection based on the action signal of the sealing unit, and performs abnormality processing if the inspection result is abnormal.

[0013] In the above solution, the specific operation of the control unit controlling the first inspection unit to inspect the heat sealing state of the carrier tape and the adhesive tape after heat sealing is that the first inspection unit photographs the image of the carrier tape and the adhesive tape after heat sealing, obtains the heat sealing indentation area s and the heat sealing indentation length sum a in the image through image analysis processing, compares the values of the heat sealing indentation area s and the heat sealing indentation length sum a with the pre-set threshold value, and obtains the inspection result of whether abnormal.

[0014] In the above solution, the sealing unit comprises a sealing body for heating and pressing the carrier tape and the adhesive tape, and a sealing drive part for driving the movement of the sealing body, the sealing body is switched between a avoiding position, a standby position and a sealing position under the driving of the sealing drive part, the sealing body contacts the adhesive tape to enable heat sealing when the sealing body is in the sealing position; the sealing body is separated from the adhesive tape to enable the carrier tape to move without being blocked when the sealing body is in the standby position; the sealing body is further away from the adhesive tape in the avoiding position than in the standby position; and the control unit controls the first inspection unit and the second inspection unit to perform the inspection based on the signal of the sealing unit switching to the standby position.

[0015] More preferably, the sealing body is a swing arm-shaped body, one end of which is hinged to the base of the equipment and the other end of which serves as a heat sealing action end; the sealing drive part comprises a rod-shaped body, a piston mechanism, an electromagnet mechanism, a spring and a lever piece, one end of the rod-shaped body is coaxially connected to the hinged end of the swing arm-shaped body, the rod-shaped body serves as a state synchronization piece of the swing arm-shaped body, and the cantilever end of the rod-shaped body serves as a driving end; the spring directly or indirectly acts on the rod-shaped body to force the driving end of the rod-shaped body to move downward; the electromagnet mechanism is arranged below the driving end and acts upward on the driving end; one end of the lever piece is also arranged below the driving end and acts upward on the driving end, and the other end of the lever piece acts on the piston mechanism, so that the piston mechanism lifts the driving end of the rod-shaped body through the lever piece; in this way, when the piston mechanism acts, the sealing body is lifted to the avoiding position, and when the piston mechanism does not act, the sealing body falls to the standby position due to the action of the spring and abuts against the electromagnet mechanism; when the electromagnet mechanism falls under action, the sealing body reaches the sealing position.

[0016] Specifically, a sensor is arranged opposite the rod-shaped body or the sealing belt body, and the sensor detects the state of the sealing belt body in the standby position and sends a signal.

[0017] In the above solution, the first inspection unit includes a sealing-after camera unit, a first illuminating device and a second illuminating device, the first illuminating device emits first inspection light in a direction with a first angle to the vertical line, the first angle is an acute angle, the second illuminating device emits second inspection light in a direction with a second angle to the vertical line, the second angle is greater than the first angle, and the wavelength of the second inspection light is different from that of the first inspection light; the control unit controls the sealing-after camera unit to capture an image of the heat-sealed carrier tape and the adhesive tape under the irradiation of the first inspection light and the second inspection light.

[0018] Further, the first inspection unit detects the state of the product based on the image component of the first inspection light in the captured image, detects the state of the carrier tape based on the image component of the second inspection light in the captured image, and detects the state of at least a part of the adhesive tape based on the image component of the first inspection light and the image component of the second inspection light in the captured image.

[0019] Still further, the first inspection unit detects the state of the part of the adhesive tape that presses the carrier tape based on the image component of the second inspection light in the captured image, and detects the state of the part of the adhesive tape that does not press the carrier tape based on both the image component of the first inspection light and the image component of the second inspection light in the captured image.

[0020] To achieve the above object, the present application adopts the technical scheme of a method for coding a tape, mainly including the following steps:

[0021] Firstly, sealing treatment, the control unit controls the sealing unit to heat seal the adhesive tape on the carrier tape on which the product is placed;

[0022] Secondly, sealing body position judgment, the control unit judges whether the sealing body is in the standby position, and if so, the next step is entered;

[0023] Thirdly, carrier tape conveying, the control unit controls the conveying unit to convey the carrier tape to a certain distance and then stop;

[0024] Fourthly, heat-sealed after inspection, the control unit controls the first inspection unit to inspect the heat sealing state of the heat-sealed carrier tape and adhesive tape, performs abnormal treatment if the inspection result is abnormal, and returns to the first step if the inspection result is normal.

[0025] In the fourth step, the control unit controls the first inspection unit to inspect the heat-sealed state of the heat-sealed carrier tape and the adhesive tape. Specifically, the first inspection unit photographs the heat-sealed carrier tape and adhesive tape, analyzes the photograph to obtain the heat-seal mark area s and the heat-seal mark length sum a, and compares the values of the heat-seal mark area s and the heat-seal mark length sum a with preset threshold values to obtain an inspection result indicating whether the heat-sealed state is normal or abnormal.

[0026] In the fourth step, the first inspection unit irradiates the heat-sealed carrier tape with first inspection light at a first angle from the vertical and second inspection light at a second angle from the vertical. The first angle is an acute angle, the second angle is greater than the first angle, and the second inspection light has a different wavelength from the first inspection light. The first inspection unit photographs the heat-sealed carrier tape and adhesive tape under the irradiation of the first and second inspection light.

[0027] Further, the first inspection unit detects the state of the product based on the image component of the first inspection light in the photographed image, detects the state of the carrier tape based on the image component of the second inspection light in the photographed image, and detects the state of at least a portion of the adhesive tape based on both the image component of the first inspection light and the image component of the second inspection light in the photographed image.

[0028] Still further, the first inspection unit detects the state of the portion of the adhesive tape that is pressed against the carrier tape based on the image component of the second inspection light in the photographed image, and detects the state of the portion of the adhesive tape that is not pressed against the carrier tape based on both the image component of the first inspection light and the image component of the second inspection light in the photographed image.

[0029] Advantages and effects of the present application:

[0030] The control unit controls the first inspection unit to perform inspection based on the operation signal of the sealing tape unit. Specifically, the control unit controls the first inspection unit to perform inspection when the operation signal of the sealing tape unit is "ON" (when the sealing body of the sealing tape unit is lifted from the position of pressing against the adhesive tape). This is the best timing for inspecting the heat-sealed state of the heat-sealed carrier tape and adhesive tape. Specifically, the timing of lifting the sealing body from the position of pressing against the adhesive tape is synchronized with the timing of stopping the carrier tape, so that inspection is performed when the carrier tape is stopped. Therefore, the accuracy of the photographing by the image device is improved, and the good and bad of the heat-seal mark is determined before entering the taping process, so that the yield of the substrate and electronic components in the taping process is improved.

DETAILED DESCRIPTION

[0040] The present application will now be described in further detail with reference to the drawings and embodiments:

[0041] Embodiment: Referring to Figures 1-6 shown:

[0042] The taping method according to the present disclosure is described below. The taping method includes a step of taping a product placed in a carrier tape by heating and pressing an adhesive tape using a taping unit 14, and a step of inspecting at least one of the carrier tape, the adhesive tape, and a product packaged with the carrier tape and the adhesive tape after the heating and pressing. The inspection is performed in accordance with the driving of the taping unit.

[0043] An embodiment of the present disclosure will now be described with reference to the drawings.

[0044] In the following description, the terms "upper step" and "lower step" are used as reference to the direction of movement of the carrier tape (carrier tape, adhesive tape, and packaging taping) unless otherwise specified.

[0045] Figure 1 A simplified schematic diagram of the device structure of an embodiment of the taping device 10 is shown. Figure 2 A perspective view of the device structure of an embodiment of the taping unit 14 is shown.Figure 3 Fig. 1 is a structural diagram showing an embodiment of the tape feeding apparatus 10 control structure.

[0046] Figure 1 The tape feeding apparatus 10 shown is provided with a conveyance unit 11, a product supply unit 12, a pre-taping inspection unit 13, a taping unit 14, a post-taping inspection unit 15, a buffer unit 16, and a tape recovery unit 17.

[0047] The conveyance unit 11 conveys the carrier tape Tc, the adhesive tape Tt, and the packaging tape Tp in accordance with the flow of the upper and lower processes under the control of the control unit 20. In this embodiment, the carrier tape Tc, the adhesive tape Tt, and the packaging tape Tp are intermittently conveyed by the conveyance unit 11. The specific method of intermittent conveyance of the carrier tape Tc, the adhesive tape Tt, and the packaging tape Tp by the conveyance unit 11 is not limited. For example, the amount of conveyance of the carrier tape Tc, the adhesive tape Tt, and the packaging tape Tp can be sensed by a sensor, and when the sensed amount reaches a predetermined value, the conveyance of the carrier tape Tc, the adhesive tape Tt, and the packaging tape Tp can be stopped or intermittently stopped. Alternatively, the carrier tape Tc, the adhesive tape Tt, and the packaging tape Tp can be moved by a driving device such as a stepping motor, and the driving device can be intermittently operated in accordance with a predetermined intermittent driving amount, so that the carrier tape Tc, the adhesive tape Tt, and the packaging tape Tp are repeatedly intermittently conveyed and intermittently stopped.

[0048] The conveyance unit 11 functionally includes a carrier tape conveyance section 45, an adhesive tape conveyance section 46, and a packaging tape conveyance section 47, as shown in Fig. 2. The carrier tape conveyance section 45, the adhesive tape conveyance section 46, and the packaging tape conveyance section 47 are shared by one or a plurality of devices. Figure 3

[0049] Figure 1 In the example shown, at least the carrier tape delivery section 21, the supply delivery section 23, the packaging tape conveyance section 24, and the packaging tape recovery section 25 are operated under the control of the control unit 20, and the carrier tape Tc is intermittently conveyed from the upper process to the lower process. Also, at least the adhesive tape delivery section 22, the packaging tape conveyance section 24, and the packaging tape recovery section 25 are operated under the control of the control unit 20, and the adhesive tape Tt is intermittently conveyed from the upper process to the lower process. Thus, at least the carrier tape delivery section 21, the adhesive tape delivery section 22, the supply delivery section 23, the packaging tape conveyance section 24, and the packaging tape recovery section 25 are operated under the control of the control unit 20, and the carrier tape Tc and the adhesive tape Tt are intermittently conveyed from the upper process to the lower process as the packaging tape Tp after heat sealing by heating and pressure.

[0050] ​The carrier tape Tc is designed to be put into the plurality of concave pockets (not shown) of the product (for example, small electronic components) and to be transported to the next process using the plurality of feed-through holes (not shown) for feeding. The positions of the concave pockets into which the products are put are arranged at equal intervals along the length of the carrier tape Tc. The feed-through holes for feeding are also arranged at equal intervals along the length of the carrier tape Tc, and the interval between adjacent holes is set according to the length of the intermittent transport distance of the carrier tape Tc, the upper tape Tt, and the packing tape Tp (for example, the amount of movement of the carrier tape for one intermittent transport).

[0051] The carrier tape Tc is held in a wound state by the carrier tape feeding section 21 and is fed by the carrier tape feeding section 21. The carrier tape Tc fed by the carrier tape feeding section 21 is wound in a roll shape by the packing tape recovery section 25 in the form of the packing tape Tp together with the upper tape after passing through the plurality of guide rollers Rg, the feeding section 21, the buffer roller Rb, and the packing tape feeding section 24, and is recovered.

[0052] The feeding section 23 is composed of a rotating body capable of rotating and a plurality of feeding protrusions arranged at equal intervals on the outer periphery of the rotating body. The shapes and sizes of the plurality of feeding protrusions are designed to fit the feed-through holes of the carrier tape Tc so that the feeding protrusions can be inserted into the feed-through holes. With the rotation of the rotating body, one or a plurality of (for example, about two to four) feeding protrusions move while entering the feed-through holes and moving inside the feed-through holes, and the carrier tape Tc is transported to the next process by the force of the feeding protrusions.

[0053] In particular, this arrangement allows the feeding protrusions to be inserted into the feed-through holes, and the relative position of the carrier tape Tc with respect to the feeding section 23 is corrected with high precision. The feeding section 23 (particularly, the feeding protrusions) functions to correct the position of the carrier tape Tc while transporting the carrier tape Tc to the next process.

[0054] The portion of the carrier tape Tc positioned by the feeding section 23 of the carrier tape Tc is provided with a concave pocket, and the product W is put into the concave pocket by the product supply unit 12.

[0055] Figure 1 The illustrated product supply unit 12 is composed of a hopper 31, a supply 32, a guide turntable 33, and an insertion unit 34. A plurality of products W put into the hopper 31 from another machine or by hand are transported from the hopper to the supply 32 to be aligned, and then to the guide turntable 33. The products W move intermittently along a circular track together with the guide turntable 33, and after being inspected by the product inspection unit 51, the products W are transported from the guide turntable 33 to the insertion unit 34. The insertion unit 34 is provided at a position opposite to the carrier tape Tc and the feeding section 23, and the products W are continuously put into the concave pockets of the carrier tape Tc from the guide turntable 33.

[0056] Further, the product supply unit 12 has a conventional device to stably perform its function, and detailed description of the product supply unit 12 is omitted here.

[0057] The carrier tape Tc and the product put in the concave pocket are sent from the feed-out section 23 to the sealing tape unit 14; the sealing tape unit 14 seals the product put in the concave pocket by heating and pressing the upper adhesive tape Tt.

[0058] The upper adhesive tape Tt is kept in a roller shape by the upper adhesive tape feed-out section 22, and is sent out by the section; the upper adhesive tape Tt sent out from the upper adhesive tape feed-out section 22 is wound and collected by the collection section 25 after passing through a plurality of guide rollers Rg, a buffer roller Rb and a package tape collection section 24.

[0059] Figure 2 The sealing tape unit 14 shown is composed of a support frame 65, a sealing tape body 41 supported by the support frame 65 and a sealing tape drive section 42; the support frame is composed of a horizontal support section extending in the horizontal direction and a vertical support section extending downward from both ends of the horizontal support section; each vertical support section is provided with a guide hole 66 extending in the height direction, and a guide bar 67 of the sealing tape body 41 can be inserted into each guide hole 66 and moved in the height direction (up and down direction).

[0060] The sealing tape body 41 is heated by being electrified under the control of the control unit 20, and the heating and pressing of the carrier tape Tc and the upper adhesive tape Tt are controlled at a proper temperature.

[0061] The sealing tape drive section 42 moves the sealing tape body 41 in the height direction (up and down direction) under the control of the control unit 20. Figure 2 The sealing tape drive section 42 shown is composed of a piston mechanism 42a and an electromagnet mechanism 42b. The sealing tape body 41 is moved between an avoiding position and a standby position under the drive of the piston mechanism 42a, and is moved between the standby position and a sealing position under the drive of the electromagnet mechanism 42b.

[0062] The sealing position mentioned here refers to the position where the sealing tape body 41 contacts above the upper adhesive tape Tt, at which time the upper adhesive tape Tt is laminated on the carrier tape Tc with the product W put in it; the position where the upper adhesive tape Tt is heat-sealed on the carrier tape Tc by heating and pressing; the standby position and the avoiding position refer to the positions where the sealing tape body 41 and the upper adhesive tape Tt (further including the carrier tape Tc with the product W put in it) are isolated; the sealing tape body 41 in the standby position is set closer to the upper adhesive tape Tt (further including the carrier tape Tc with the product W put in it) than the sealing tape body 41 in the avoiding position.

[0063] The carrier tape Tc and the top adhesive tape Tt travel below the sealing tape body 41 in an overlapping state. When they are below the sealing tape body 41, the sealing tape body 41 at the sealing position performs one or more heating and pressurization treatments on them. After the product W is placed in, the heat-sealed carrier tape Tc and top adhesive tape Tt are transported to the next process as packaging tape Tp.

[0064] Specifically, such as Figure 6 As shown, another specific embodiment of the sealing tape unit 14 is as follows: the sealing tape body is a swing arm-shaped body 71, one end of which is hinged to the equipment base, and the other end serves as the heat sealing end 711; the sealing tape driving part includes a rod-shaped body 72, a piston mechanism 73, an electromagnet mechanism 74, a spring, and a lever 75. One end of the rod-shaped body 72 is coaxially connected to the hinge end of the swing arm-shaped body 71, and the rod-shaped body 72 serves as a state synchronization element for the swing arm-shaped body 71, while the cantilever end of the rod-shaped body 72 serves as the driving end 721; the spring acts directly or indirectly on the rod-shaped body 72, forcing the driving end 721 of the rod-shaped body 72 to move downward; the electromagnet mechanism 74 is located below the driving end 721 and acts upward on the driving end 721. 1; The lever 75 is hinged to the equipment base in the middle, and one end of it is located below the drive end 721 and acts upward on the drive end 721. The piston mechanism 73 acts on the other end of the lever 75, so that the piston mechanism 73 lifts the drive end 721 of the rod-shaped body 72 through the lever 75. Thus, when the piston mechanism 73 is in action, the sealing tape (i.e., the heat-sealing end 711 of the swing arm-shaped body 71) is raised to the avoidance position. When the piston mechanism 73 is not in action, the sealing tape (i.e., the heat-sealing end 711 of the swing arm-shaped body 71) falls to the standby position due to the action of the spring and abuts against the electromagnet mechanism 74. When the electromagnet mechanism 74 moves and falls, the sealing tape (i.e., the heat-sealing end 711 of the swing arm-shaped body 71) reaches the sealing position. A sensor 76 is provided for the rod-shaped body 72 or the sealing tape body, so that the sensor 76 can directly or indirectly detect that the sealing tape body (i.e., the heat sealing end 711 of the swing arm-shaped body 71) is in the standby position and send a signal.

[0065] like Figure 1 The processed packaging tape Tp is sent from the sealing unit 14 to the packaging tape recycling unit 25 via the buffer unit 16 (buffer roller Rb) and the packaging tape conveyor 24; in addition, the buffer unit 16 can be set as needed to adjust the tension of the carrier tape Tc located between the feed delivery unit 23 and the packaging tape delivery unit 24 and the packaging tape Tp located between the sealing unit 14 and the packaging tape conveyor 24.

[0066] This ensures that the carrier tape Tc located between the feeding section 23 and the packaging tape feeding section 24 and the packaging tape Tp located between the sealing unit 14 and the packaging tape conveyor 24 maintain sufficient tension, preventing slack. Therefore, the action of the insertion unit 34 (product supply unit 12) to supply the product W to the concave pocket of the carrier tape Tc, and the heating and pressurizing treatment of the carrier tape Tc and the top adhesive tape Tt by the sealing unit 14 can better achieve stable positional accuracy.

[0067] The processed packaging tape Tp is thus recovered in a wound state by the packaging tape recycling section 25; in addition, when the packaging tape Tp is between the packaging tape conveying section 24 and the packaging tape recycling section 25, the tension can be maintained to a sufficient degree or the tension can be relaxed.

[0068] The tape-tapping equipment 10 of this embodiment, having the above-described configuration, is equipped with a carrier tape Tc and a pre-sealing inspection unit (second inspection unit) 13 for inspecting the upper adhesive tape Tt before heating and pressurizing, and a post-sealing inspection unit (first inspection unit) 15 for inspecting the carrier tape Tc after heating and pressurizing the upper adhesive tape; the pre-sealing inspection unit 13 and the post-sealing inspection unit 15 perform inspections under the control of the control unit 20.

[0069] Figure 1 In the example, the pre-sealing inspection unit 13 is equipped with a product inspection unit 51 and a material supply inspection unit 56.

[0070] Product inspection unit 51 inspects product W in the conveying state of guide turntable 33, such as... Figure 3 In the example shown, a product power-on unit 52 and a product camera unit 53 are provided. The product power-on unit 52 applies current to the product W to check for defects in the circuit of the product W. The product camera unit 53 takes a picture of the product W and checks for appearance defects (such as scratches or abnormal shapes) of the product W by analyzing the captured image. The image analysis can be performed by the product inspection unit 51 and the analysis result can be transmitted to the control unit 20. Alternatively, the image analysis can be performed by the control unit 20.

[0071] like Figure 3 As shown in the example, the material feeding inspection unit 56 is equipped with a pre-sealing inspection controller 57 and a pre-sealing camera unit 58. Under the control of the pre-sealing inspection controller 57 (and consequently, under the control of the control unit 20), the pre-sealing camera unit 58 photographs the product W and the carrier tape Tc placed on it, acquiring an image. The pre-sealing camera unit 58 photographs the product W and the carrier tape Tc covered by the adhesive tape. Under the control of the control unit 20, the pre-sealing inspection controller 57 analyzes the image captured by the pre-sealing camera unit 58 to check for any abnormalities in the product W and / or the carrier tape Tc. Alternatively, the analysis and inspection of this photographed image can also be performed by the control unit 20.

[0072] As Figure 3 illustrated, the post-sealing inspection unit 15 is provided with a post-sealing inspection controller 61 and a post-sealing imaging section 62, which, under the control of the post-sealing inspection controller 61 (and further under the control of the control unit 20), images and acquires an image of the packaging tape Tp (i.e., the heat-pressing treated carrier tape Tc, the adhesive tape Tt, and the product W). Since the adhesive tape Tt is made of a transparent material, the product W in the concave pocket of the carrier tape Tc can be imaged. The post-sealing inspection controller 61, under the control of the control unit 20, controls the post-sealing imaging section 62 to image and acquire an image, which is analyzed. This analysis and inspection of the imaged image can be performed by the control unit 20 to check the heat-pressing treated carrier tape Tc, the adhesive tape Tt, and the product W for any abnormality.

[0073] Specifically, the post-sealing inspection unit (i.e., the first inspection unit) 15, as Figure 7 illustrated, includes the post-sealing inspection controller 61, the post-sealing imaging section 62, a first illuminating device 63, and a second illuminating device 64. The first illuminating device 63 emits a first inspection light DL1 in a direction that makes a first angle θ1 with a vertical line, the first angle θ1 being an acute angle. The second illuminating device emits a second inspection light DL2 in a direction that makes a second angle θ2 with the vertical line, the second angle θ2 being greater than the first angle θ1, and the second inspection light DL2 has a different wavelength than the first inspection light DL1. More specifically, as Figure 7 illustrated, the post-sealing imaging section 62 is positioned vertically above the imaging position and images downward along the vertical line, i.e., the center line Dc, Lv of the post-sealing imaging section 62 is the vertical line. Specifically, the first angle θ1 is preferably 20-30 degrees, and the second angle θ2 is 90 degrees. The first illuminating device 63 is symmetrically arranged on the left and right sides of the post-sealing imaging section 62, and the second illuminating device 64 is also symmetrically arranged on the left and right sides of the post-sealing imaging section 62.

[0074] The post-sealing inspection controller 61 controls the post-sealing imaging section 62 to capture images of the heat-sealed carrier tape Tc and the adhesive tape Tt under the irradiation of the first inspection light and the second inspection light, under the control of the control unit 20. Preferably, the control unit 20 controls the post-sealing inspection controller 61 to detect the state of the product W based on the image component of the first inspection light in the captured image, to detect the state of the carrier tape Tc based on the image component of the second inspection light in the captured image, and to detect the state of at least a portion of the adhesive tape Tt based on both the image component of the first inspection light and the image component of the second inspection light in the captured image. Preferably, the control unit controls the post-sealing inspection controller to detect the state of the portion of the adhesive tape Tt that is pressed against the carrier tape based on the image component of the second inspection light in the captured image, and to detect the state of the portion of the adhesive tape Tt that is not pressed against the carrier tape based on both the image component of the first inspection light and the image component of the second inspection light in the captured image.

[0075] The specific method of analyzing and inspecting the captured images is not limited, and a typical method is to capture images of the carrier tape Tc, the adhesive tape Tt, the product W, and / or the packaging tape Tp in a normal state without defects in advance, and to use the captured images as reference images. The captured images are compared with the reference images to determine whether there is any abnormality. A more specific method is that the control unit 20 controls the post-sealing inspection unit 15 to capture images of the heat-sealed carrier tape and the adhesive tape, and obtains an image as shown in FIG. 8. The image is analyzed and processed to obtain the area s of the heat-seal indentation 78 and the total length a of the heat-seal indentation 78 in the image. The values of the area s of the heat-seal indentation 78 and the total length a of the heat-seal indentation 78 are compared with the threshold values set in advance, and the inspection result of whether there is any abnormality is obtained. Figure 5

[0076] The area s and the total length a of the heat-seal indentation 78 generally represent the quality of the heat sealing. For example, when the heat-seal indentation 78 has a break, the values of the area s and the total length a of the heat-seal indentation 78 will decrease. When the width of the heat-seal indentation 78 at a certain position is too narrow (i.e., represents a virtual connection), the value of the area s of the heat-seal indentation 78 will also change. Therefore, the quality of the heat sealing can be generally reflected by the area s and the total length a of the heat-seal indentation 78.

[0077] Specifically, an image of the packaging tape Tp in a normal state without defects is captured in advance, the captured image is binarized to be converted into a black-and-white image, and the image is analyzed and processed to obtain the values of the area s of the heat-seal indentation 78 and the total length a of the heat-seal indentation 78 at a specified position in the image. The values of the area s and the total length a of the heat-seal indentation 78 are directly set as the threshold values in advance, or the values of the area s and the total length a of the heat-seal indentation 78 are substituted into a preset formula to obtain a value as the threshold value, which is set in advance. When the inspection is performed on the device, an image of the packaging tape Tp is captured (as shown in FIG. 8), and the image is analyzed and processed to obtain the values of the area s of the heat-seal indentation 78 and the total length a of the heat-seal indentation 78 at a specified position in the image. The values of the area s and the total length a of the heat-seal indentation 78 are compared with the threshold values set in advance, and the inspection result of whether there is any abnormality is obtained. Figure 5 ​The image is binarized to convert it into a black-and-white image, and the image analysis is performed to obtain the values of the seal mark area s and the total length a of the heat seal mark 78 at the prescribed position of the image. These values are compared with the set threshold values, or the values are substituted into the above-described predetermined formula to obtain a result, which is compared with the predetermined value. If the result is within the allowable range, the inspection result is determined to be normal, and the device is allowed to continue operation. If the result is abnormal, an abnormality is processed.

[0078] In this example, the inspection by the pre-sealing inspection unit 13 (product inspection unit 51 and supply inspection unit 56) and the post-sealing inspection unit 15 is performed during the intermittent stop of the product W and the carrier tape Tc.

[0079] The control unit 20 controls each part of the above-described taping device 10 (the conveying unit 11, the product supply unit 12, the pre-sealing inspection unit 13, the sealing unit 14, the post-sealing inspection unit 15, the buffer unit 16, and the taping recovery unit 17). Figure 3 The control unit 20 shown in the drawing is a single structure, which can be constituted by a single control section or a combination of a plurality of control sections. Therefore, a specific control section can be provided for each unit, or one control section can be provided for a plurality of units.

[0080] The control unit 20 of this embodiment controls the post-sealing inspection unit 15 so that the post-sealing inspection unit 15 (first inspection unit) performs inspection in accordance with the driving of the sealing unit 14. The control unit 20 can transmit a driving signal for performing inspection to the post-sealing inspection unit 15 in accordance with the driving signal transmitted to the sealing unit 14, or the control unit 20 can receive a signal from the sealing unit 14 and transmit a driving signal for performing inspection to the post-sealing inspection unit 15 in accordance with the received signal. Thus, the post-sealing inspection unit 15 performs inspection in accordance with the sealing process of the sealing unit 14, and the state of the packaging tape Tp (carrier tape Tc, adhesive tape Tt, and product W) can be confirmed at the optimum timing.

[0081] The control unit 20 controls the carrier tape conveying section 45 so that the conveying of the carrier tape Tc performed by the carrier tape conveying section 45 of the conveying unit 11 is performed in accordance with the driving of the sealing unit 14. The control unit 20 can transmit a driving signal for intermittently conveying the carrier tape Tc, adhesive tape Tt, and packaging tape Tp to the conveying unit 11 in accordance with the driving signal transmitted to the sealing unit 14, or the control unit 20 can receive a signal from the sealing unit 14 and transmit a driving signal for intermittently conveying the carrier tape Tc, adhesive tape Tt, and packaging tape Tp to the conveying unit 11 in accordance with the received signal.

[0082] In particular, in this example, the control unit 20 controls the carrier tape conveying section 45 to repeatedly intermittently convey and intermittently stop the carrier tape Tc by the carrier tape conveying section 45 of the conveying unit 11, and the carrier tape Tc is intermittently conveyed by a set movement amount. Thus, the intermittent conveyance of the carrier tape (carrier tape Tc, adhesive tape Tt, and packaging tape Tp) is performed in conjunction with the sealing tape processing operation of the sealing tape unit 14, and the carrier tape can be stably conveyed without hindrance at the appropriate timing.

[0083] Next, a method of packaging (particularly, the heating and pressing process and the inspection process) performed by the packaging apparatus 10 described above will be described with an example.

[0084] Figure 4 By way of an example, a flowchart of the method of packaging (particularly, the heating and pressing process and the inspection process) is shown.

[0085] A method of packaging, mainly comprising the following steps:

[0086] First, sealing tape processing S1, the control unit controls the sealing tape unit to heat seal the adhesive tape to the carrier tape on which the product is placed;

[0087] Second, sealing tape body position determination S2, the control unit determines whether the sealing tape body is in a standby position, and if it is in the standby position, proceeds to the next step;

[0088] Third, carrier tape conveying S4-S6, the control unit controls the conveying unit to convey the carrier tape to a certain distance and then stop;

[0089] Fourth, post-sealing inspection S8-S9, the control unit controls the first inspection unit to inspect the heat sealing state of the carrier tape and the adhesive tape after heat sealing, and if the inspection result is abnormal, performs abnormality processing, and if the inspection result is normal, returns to the first step.

[0090] The specific operation of the image analysis in the fourth step of the post-sealing inspection is as follows: the first inspection unit takes an image of the carrier tape and the adhesive tape after heat sealing, and obtains the heat sealing indentation area s and the heat sealing indentation length sum a in the image through image analysis processing. The values of the heat sealing indentation area s and the heat sealing indentation length sum a are compared with the pre-set threshold value, and the inspection result of whether it is abnormal is obtained.

[0091] Further specific methods are described as follows:

[0092] The sealing tape unit 14 heats and presses the adhesive tape against the carrier tape Tc on which the product W is placed, and performs sealing tape processing Figure 4(S1). Specifically, the piston mechanism 42a and the electromagnet mechanism 42b put the sealing body 41 in a standby position, with the carrier tape Tc, the top adhesive tape Tt, and the portion of the product W to be sealed below the sealing body 41. The electromagnet mechanism 42b then moves the sealing body 41 from the standby position to the sealing position, sealing the portion to be sealed. The product W and the carrier tape Tc are heat-sealed by the top adhesive tape to form a packaging tape Tp.

[0093] Next, the sealing tape body 41 is moved from the sealing position to the standby position by the electromagnet mechanism 42b, creating a distance between the sealing tape body 41 and the target portion of the carrier tape Tc and the upper adhesive tape Tt. Next, the control unit 20 determines whether the sealing tape body 41 is in the standby position. Figure 4 (S2). The specific method for determining whether the sealing tape 41 is in the standby position is not limited. For example, the determination can be made based on the inspection results of the sensor (not shown in the figure).

[0094] When the sealing tape 41 is determined to be not in the standby position ( Figure 4 When the sealing tape 41 malfunctions (and consequently, the sealing of the carrier tape Tc and the upper adhesive tape Tt is more likely to malfunction), the control unit 20 performs abnormal processing ( Figure 4 The S3) will notify the manager of the tape and reel equipment 10 of any defects.

[0095] When the sealing tape 41 is determined to be in the standby position ( Figure 4 (S2 of Y), control unit 20, through control conveying unit 11, intermittently conveys the carrier tape (carrier tape Tc, top adhesive tape Tt, and packaging tape Tp) to the next process ( Figure 4 S4). And the control unit 20 stops the carrier belt intermittently ( Figure 4 S5), to determine whether the intermittent transfer amount of the carrier belt is appropriate ( Figure 4 (S6). The method for determining whether the intermittent transfer amount of the carrier tape is appropriate is not limited; for example, it can be determined based on the inspection results of sensors that are not shown in the figure.

[0096] When the intermittent transfer amount of the carrier tape is determined to be inappropriate ( Figure 4 (S6 of N), the control unit 20 notifies the manager of the abnormality in the intermittent conveying of the carrier belt by implementing abnormality handling. Figure 4 (S7).

[0097] When the intermittent transfer amount of the carrier tape is determined to be appropriate ( Figure 4 The control unit 20, by controlling the pre-sealing inspection 13 (especially the feeding inspection unit 56) and the post-sealing inspection unit 15, uses the pre-sealing camera 58 and the post-sealing camera 62 to take pictures.

[0098] And the control unit 20 analyzes the images taken by the pre-sealing camera 58 and the post-sealing camera 62 by controlling the pre-sealing controller 57 and the post-sealing inspection controller 61. In addition, the object that has been subjected to the sealing process by the sealing unit 14 before the imaging by the post-sealing camera 62 is not necessarily imaged. Therefore, the object of the imaging process and the image analysis process performed by the post-sealing inspection unit 15 in the above steps S8 and S9 is not necessarily the same as the object of the sealing process in the above step S1.

[0099] In addition, Figure 5 In the steps S9 and S10, the control unit 20 controls the post-sealing inspection unit 15 to inspect the heat-sealed state of the sealing tape Tc and the adhesive tape Tt after the heat sealing. The specific operation is that the post-sealing inspection unit 15 takes images of the heat-sealed sealing tape Tc and adhesive tape Tt (i.e., the packaging tape Tp) as shown in Figure 4 Figure 4 Figure 4

[0100] When the sealing tape Tc, the adhesive tape Tt, and / or the product W are determined to be abnormal (N in the step S10), the control unit 20 performs an abnormality process (S11) and notifies the manager of the abnormality of the sealing tape Tc, the adhesive tape Tt, and / or the product W. Figure 4 Figure 4

[0101] For example, by analyzing the images taken by the pre-sealing camera 58, it is determined whether the sealing tape Tc and / or the product W before the sealing process is appropriate, and if it is determined to be inappropriate, the manager is notified. In addition, by analyzing the images taken by the post-sealing camera 62, it is determined whether the sealing tape Tc, the adhesive tape Tt, and / or the product W (i.e., the packaging tape Tp) after the sealing process is appropriate, and if it is determined to be inappropriate, the manager is notified.

[0102] In addition, when the sealing tape Tc, the adhesive tape Tt, and the product W (i.e., the packaging tape Tp) are determined to be appropriate (Y in the step S10), the heating and pressing process and the inspection process related to the current object part in the sealing tape Tc, the adhesive tape Tt, and the product W (i.e., the packaging tape Tp) are ended. Figure 4

[0103] ​​​​​​Therefore, the post-sealing inspection unit 15 inspects either the carrier tape Tc after heating and pressurizing, or the product W packaged with the top adhesive tape Tt. In particular, in this embodiment, as described above, this inspection is performed based on the drive of the sealing unit 14. Furthermore, the pre-sealing inspection unit 13 (particularly the feeding inspection unit 56) inspects either the carrier tape Tc before heating and pressurizing, or the product W placed inside the carrier tape Tc.

[0104] Furthermore, the control unit 20 determines whether the sealing process of the carrier tape Tc, the adhesive tape Tt, and the product W is complete (i.e., whether there are any items that still require a heating and pressurizing process). Figure 4 S12). When it is determined that the sealing process has not ended ( Figure 4 The above series of processing steps (refer to S1 to S11) are repeated to perform heating and pressurization processes and inspection processes on the parts that still need to be heated and pressurized (carrier tape Tc, adhesive tape Tt and product W).

[0105] When the carrier tape Tc, the top adhesive tape Tt, and the sealing tape of the product W are respectively determined to be at the end ( Figure 4 (S12, Y), the control unit 20 determines whether the inspection and processing of the carrier tape Tc, the upper adhesive tape Tt, and the product W is complete (i.e., whether there are any objects that still need to undergo inspection). Figure 4 (S13). If the inspection process is determined to be incomplete ( Figure 8 The above series of processing steps (refer to S4 to S12) are repeated, and an inspection process is carried out on the parts that still need to be heated and pressurized (carrier tape Tc, adhesive tape Tt and product W).

[0106] When the inspection process is determined to be completed ( ​ The series of tape-making methods (especially the heating and pressing process and the inspection process) are completed by S13Y.

[0107] Furthermore, the above-mentioned exception handling S3, S7, and S11 can be implemented using any method. For example, an exception notification can be directly displayed to the manager (e.g., a visual notification via a display screen and / or an auditory notification via a speaker), or the exception can be indirectly notified to the manager by stopping the operation of the tape-and-reel device 10.

[0108] In the fourth step, after heat sealing, the inspection process is detailed as follows: ​As shown, the fourth step of the post-sealing inspection unit (i.e., the first inspection unit) 15 irradiates the heat-sealed packaging tape Tp with the first illumination device 63 to emit the first inspection light DL1 in a direction at a first angle from the vertical line, and with the second illumination device 64 to emit the second inspection light DL1 in a direction at a second angle from the vertical line. In this state of irradiation, the post-sealing inspection unit (i.e., the first inspection unit) 15 captures an image of the heat-sealed carrier tape and the adhesive tape under the irradiation of the first inspection light DL1 and the second inspection light DL2.

[0109] Then, the captured image is divided into a first inspection light image, a second inspection light image, and a composite inspection light image according to the wavelengths of the light sources.

[0110] Next, a first image processing is performed based on the first inspection light image, a second image processing is performed based on the second inspection light image, and a third image processing is performed based on the composite inspection light image to perform the inspection.

[0111] When an abnormality is detected, an alarm is issued.

[0112] As described above, with the use of the above-described taping apparatus 10 and taping method, the post-sealing inspection unit 15 performs the inspection based on the driving of the sealing unit 14, and performs the inspection of the taping packaging of the product W after the sealing process, thereby improving the quality of the packaging tape Tp.

[0113] In addition, the pre-sealing inspection unit 13 and the post-sealing inspection unit 15 perform the inspection before and after the sealing process. When a defect is found in the inspection, the taping apparatus can be immediately stopped, and the defective part can be immediately removed. In the conventional apparatus and method, the inspection of the taping member and the sealing operation of the taping apparatus are not associated, and the inspection is not performed before and after the sealing process.

[0114] In this case, even if a defect occurs in the carrier tape Tc, the adhesive tape Tt, and / or the product W, the taping apparatus 10 cannot be stopped to deal with the defect, and the taping apparatus is operated in the state where the defect is not corrected. As a result, for example, the packaging tape Tp wound (finished roll) in the packaging tape recovery unit 25 needs to be unwound to confirm the defective part, and after the confirmation, the packaging tape Tp needs to be rewound, thereby unnecessarily adding a process.

[0115] In addition, in the use of the above-described taping apparatus 10 and taping method, the carrier tape Tc is transported by the transport unit 11 based on the driving signal of the sealing unit 14, and thus the intermittent transport and intermittent stop of the carrier tape Tc (and the intermittent transport and intermittent stop of the adhesive tape Tt and the packaging tape Tp) can be performed at the optimum timing in response to the operation of the sealing unit 14.

[0116] Variation:

[0117] The pre-taping inspection unit 13 and the post-taping inspection unit 15 according to the above-described embodiments perform inspection based on analysis of the captured images, and can perform other arbitrary inspection. For example, the pre-taping inspection unit 13 and the post-taping inspection unit 15 can acquire an X-ray captured image instead of a visible light captured image, and perform inspection based on analysis of the X-ray captured image. Alternatively, the pre-taping inspection unit 13 and the post-taping inspection unit 15 can perform inspection based on a result of measurement of an arbitrary state quantity of the carrier tape Tc, the adhesive tape Tt, and / or the product W using a sensor.
