Detailed Description

In order to explain technical contents, structural features, and effects of the present invention in detail, the following detailed description is given with reference to the embodiments and the accompanying drawings.

Referring to fig. 1 to 4 and fig. 6, a pressing device 100 of the present invention includes a device frame 10, a pressing head 20, a driver 30, a positioning mold 40 and a touch switch 50. The positioning mold 40 is installed on the device frame 10 and has a positioning support cavity 41 for positioning and supporting the product 200 to be pressed, preferably, the positioning support cavity 41 is a square cavity for matching with the square product 200 to be pressed, and naturally, the shape of the positioning support cavity 41 may be other, which is determined by the shape of the product 200 to be pressed, so that the invention is not limited thereto. The actuator 30 is mounted on the device frame 10, and preferably, the actuator 30 is an air cylinder to simplify the structure for providing the linear driving force, and of course, the actuator 30 may also be a hydraulic cylinder to provide a larger linear driving force according to actual needs, so that the invention is not limited thereto. The pressing head 20 is connected to the output end of the driver 30, and preferably, the pressing head 20 is installed at the output end of the driver 30, so that the pressing head 20 slides into or out of the positioning and supporting cavity 41 under the driving of the driver 30, thereby meeting the requirement that the pressing head 20 presses the product 200 to be pressed in the positioning and supporting cavity 41. The touch switch 50 includes a seesaw 51 and a contact terminal 52, the seesaw 51 is mounted on the positioning mold 40 and extends into the positioning support cavity 41, preferably, the seesaw 51 is embedded in the middle of the positioning mold 40, so that the assembly between the seesaw 51 and the positioning mold 40 is more compact, and the seesaw 51 is located in the middle of the positioning support cavity 41, of course, the seesaw 51 can also be mounted on the device frame 10 according to actual requirements, as long as the seesaw 51 mounted on the device frame 10 is ensured to extend into the positioning support cavity 41, so that the invention is not limited thereto; the seesaw 51 is switched between a seesaw position and a pressing position relative to the positioning die 40 around a seesaw center line C arranged along the length direction of the device frame 10, the seesaw 51 always tends to be switched to the seesaw position, and the contact terminal 52 is located below the seesaw 51; therefore, in the process of placing the product 200 to be pressed into the positioning and supporting cavity 41, the seesaw 51 pushed by the product 200 to be pressed is switched from the seesaw position shown in fig. 5 to the push-down position shown in fig. 1, and the seesaw 51 pushed to the push-down position is abutted against the contact terminal 52, so as to switch the on/off state of the touch switch 50, so that the touch switch 50 is in the closed state at this time to open the driver 30, and the driver 30 drives the pressing head 20 to move for pressing the product 200 to be pressed.

In combination with fig. 9, in order to make the laminating apparatus 100 of the present invention further have a fool-proof function, the laminating apparatus 100 of the present invention further includes a controller 60 and a sensor 70 electrically connected to the controller 60. The controller 60 is disposed on the device frame 10, and the device frame 10 provides an installation place for the controller 60, and the controller 60 is further electrically connected to the touch switch 50 for receiving the opening/closing state signal fed back by the touch switch 50. The sensor 70 is installed at the positioning mold 40, the sensor 70 further corresponds to the handle fastening position 210 of the product 200 to be pressed which is placed in the positioning support cavity 41 in the forward direction, so that the handle fastening position 210 of the product 200 to be pressed can more reliably shield the sensor 70 at the positioning mold 40, preferably, the sensor 70 is selected as a photoelectric switch to improve the reliability of the operation of the sensor 70, and of course, according to actual needs, the sensor 70 can also be installed on the device frame 10 as long as the sensor 70 installed on the device frame 10 further corresponds to the handle fastening position 210 of the product 200 to be pressed which is placed in the positioning support cavity 41 in the forward direction, so that the present invention is not limited thereto. When the product 200 to be pressed is placed in the positioning and supporting cavity 41 in the forward direction, the product 200 to be pressed pushes the touch switch 50 to switch the open/close state, and simultaneously, the sensor 70 is shielded by the handle 210, at this time, the touch switch 50 feeds back the open/close state signal and the shielding signal of the sensor 70 to the controller 60, and the controller 60 controls the driver 30 to drive the pressing head 20 to perform pressing movement only under the open/close state signal and the shielding signal received by the controller 60; on the contrary, in the process of placing the product 200 to be pressed in the positioning and supporting cavity 41 reversely, since the product 200 to be pressed placed reversely can make the handle 210 and the sensor 70 dislocate without shielding the sensor 70, the sensor 70 does not feed back a shielding signal to the controller 60, and the product 200 to be pressed placed reversely can only push the touch switch 50 to switch the on-off state, and the touch switch 50 sends an on-off state signal to the controller 60, therefore, after the product 200 to be pressed is placed in the positioning and supporting cavity 41 reversely, the controller 60 at this time can not control the driver 30 to drive the pressing head 20 to perform the pressing movement because of receiving the on-off state signal, so that the product 200 to be pressed has the foolproof function to prevent the defective product of the product 200 to be pressed. More specifically, the following:

as shown in fig. 1 to 5, the positioning die 40 further has an avoiding space 42 for accommodating the hand fastening position 210, the avoiding space 42 is located beside the positioning and supporting cavity 41, and the sensor 70 is located in the avoiding space 42, so that the sensor 70 is closer to the position of the hand fastening position 210 when the product 200 to be pressed is placed in the positioning and supporting cavity 41 in the forward direction, and the hand fastening position 210 more reliably shields the sensor 70; preferably, the avoiding space 42 is located at a corner of the positioning die 40 to better match the product 200 to be pressed; for example, the positioning mold 40 has a square structure, but is not limited thereto, and may be designed into other shapes according to actual needs.

As shown in fig. 5 to 7, the touch switch 50 further includes a switch frame 53 mounted on the positioning mold 40, preferably, the switch frame 53 is embedded in the positioning mold 40, but not limited thereto; the seesaw 51 is pivotally connected to the switch frame 53 around the seesaw center line C, preferably, the seesaw 51 is pivotally connected to the switch frame 53 through the shaft 55, such that the shaft 55 forms the seesaw center line C, and the shaft 55 and the seesaw 51 can be integrated or separated, so as not to be limited thereto; and the seesaw swing part 51 is separated into a seesaw section 51a and a balance weight section 51b by the seesaw swing central line C, the seesaw section 51a is switched to a seesaw position extending into the positioning support cavity 41 under the gravity action of the balance weight section 51b, so that the seesaw swing part 51 is automatically reset to the seesaw position under the pushing of the product 200 to be pressed away, the resetting is more convenient, the structure is simpler, and conditions are created for the pressing operation of the product 200 to be pressed next time. Specifically, the raised section 51a has a pushing column 511 extending upward into the positioning and supporting cavity 41, so that the product 200 to be pressed can push the raised piece 51 and the raised piece 51 can extend into the positioning and supporting cavity 41. For example, the switch frame 53 includes a bottom plate 53a and a cover plate 53b each having an avoiding space 54, the cover plate 53b covers the bottom plate 53a, the seesaw 51 is located at the avoiding space 54, the pushing column 511 upwardly passes through the cover plate 53a and then extends into the positioning support cavity 41, and the contact terminal 52 is inserted through the bottom plate 53a, so that the seesaw 51 is hidden in the switch frame 53, thereby preventing the seesaw 51 from being interfered by the outside. It can be understood that, according to actual needs, the seesaw center line C may also be arranged along the width direction of the device frame 10, and the avoiding space 54 may be only opened at the bottom plate 53a or the cover plate 53 b; in addition, the seesaw-like swing member 51 may have a tendency to be switched to the seesaw position by the weight of the user, and the seesaw-like swing member 51 may have a tendency to be switched to the seesaw position by the elastic member, which is not limited thereto.

Specifically, the output end of the driver 30 on the door-shaped upright arm 10b is arranged downward, which saves the connecting space between the ram 20 and the driver 30, but is not limited thereto. For example, the top end portion of the base body 10a is opened with a first adjusting long hole 12 arranged along the length direction thereof for adjusting the position of the driver 30 at the base body 10a on the base body 10a, and the cross beam 11 is opened with a second adjusting long hole 13 arranged along the length direction thereof for adjusting the position of the driver 30 at the gate-shaped upright arm 10b on the gate-shaped upright arm 10b, but is not limited thereto. It will be understood that when the apparatus frame body 10 is designed to include the base body 10a and the gate-shaped standing arm 10b, the positioning die 40 is installed at the top end of the base body 10a at this time, but is not limited thereto.

As shown in fig. 1 to 4 and fig. 8, the pressing device 100 of the present invention further includes an indicator 86 mounted on the device frame 10, the indicator 86 is electrically connected to the controller 60, preferably, the indicator 86 is located at the top end of the base body 10a, so that the indicator 86 indicates when the product 200 to be pressed is placed in the positioning and supporting cavity 41 in the forward direction, and plays a role of reminding an operator; of course, the indicator lamp 86 may be disposed on the door-shaped upright arm 10b, and is not limited thereto. It will be appreciated that the indicator light 86 may be deleted at this point when the prompting action of the indicator light 86 is not required.

As shown in fig. 1 to 4 and fig. 9, the stitching device 100 of the present invention further includes a time delay relay 81, an intermediate relay 82, a solenoid valve 83, a first pipeline 84 for performing an extending movement on the driver 30, and a second pipeline 85 for controlling a retracting movement of the driver 30; the solenoid valve 83, the delay relay 81 and the intermediate relay 82 are respectively mounted on the device frame 10 and electrically connected to the controller 60, and preferably, the solenoid valve 83, the delay relay 81 and the intermediate relay 82 are respectively mounted in the base body 10a of the device frame 10 and hidden by the base body 10a, so as to prevent external interference and make the appearance of the device frame 10 simpler, but not limited thereto; the controller 60 controls the solenoid valve 83 to open and close the first pipeline 84 and the second pipeline 85 through the delay relay 81 and the intermediate relay 82, so that the pressing of the product 200 to be pressed, the shaping after the pressing and the resetting of the driver 30 are realized by the cooperation of the solenoid valve 83, the delay relay 81 and the intermediate relay 82, and the pressing efficiency of the product 200 to be pressed is improved, but not limited thereto. In order to display the air pressure, an air pressure gauge 87 is attached to the door-shaped vertical arm 10 b. It should be noted that the connections among the delay relay 81, the intermediate relay 82 and the solenoid valve 83 are well known in the art and therefore will not be described in detail herein.

As shown in fig. 3 and 4, in order to facilitate the connection between the pressing device 100 of the present invention and the external commercial power, a power switch 92 and a power socket 93 are installed on the rear sidewall of the base 10a, and the power switch 92 is used to control the on/off of the commercial power supplied to the pressing device 100 of the present invention; to further facilitate the operation of the pressing device 100 of the present invention by the operator, an actuating button 94 is mounted on the left and/or right side wall of the base body 10a, and the actuating button 94 is used for electrically connecting with the controller 60 and inputting a triggering signal to the controller 60, but is not limited thereto.

The working principle of the pressing device of the present invention is explained with reference to the accompanying drawings: in the process that the product 200 to be pressed is placed in the positioning and supporting cavity 41 in the forward direction, the product 200 to be pressed pushes the touch switch 50 to switch the on-off state, specifically, the product 200 to be pressed pushes the seesaw 51 to switch from the raised position shown in fig. 5 to the pressed position shown in fig. 1, the seesaw 51 at the pressed position pushes against the contact terminal 52, so as to switch the on-off state of the touch switch 50, and the touch switch 50 feeds back the on-off state signal to the controller 60; meanwhile, the handle 210 of the product 200 to be pressed also shields the sensor 70, and the sensor 70 feeds back a shielding signal to the controller 60; the controller 60 controls the indicator lamp 86 to perform indicating work after receiving the opening/closing state signal and the shielding signal at the same time; at this time, when the operator operates the start button 94, the controller 60 controls the driver 30 to drive the pressing head 20 to press the product 200 to be pressed according to the trigger signal of the start button 94; in the process of reversely placing the product 200 to be pressed in the positioning and supporting cavity 41, the handle 210 of the product 200 to be pressed and the sensor 70 are dislocated, so that the sensor 70 cannot be shielded, that is, the handle 210 of the product 200 to be pressed and placed in the positioning and supporting cavity 41 reversely cannot trigger the sensor 70 to work, and the controller 60 receives the on-off state signal fed back by the touch-press switch 50, so that the controller 60 makes the indicator lamp 86 in the non-indicating state, and therefore, even if the start button 94 is operated, the controller 60 cannot control the driver 30 to drive the press head 20 to perform the pressing motion according to the signal of the start button 94. It can be understood that, since the product 200 to be pressed needs to be pressure-maintaining and shaped after being pressed, when the controller 60 controls the driver 30 to drive the pressing head 20 to perform the pressing motion on the product 200 according to the trigger signal of the start button 94, the controller 60 controls the electromagnetic valve 83 to open and close the first pipeline 84 and the second pipeline 85 through the cooperation of the delay relay 81 and the intermediate relay 82, so as to control the driver 30 to drive the pressing head 20 to perform the pressing motion; when the product 200 to be pressed does not need to be pressure-maintaining and shaped, the controller 30 directly controls the electromagnetic valve 83 to open and close the first pipeline 84 and the second pipeline 85, but not limited thereto.

Compared with the prior art, the pressing device 100 of the invention further comprises a touch switch 50, the touch switch 50 comprises a seesaw 51 and a contact terminal 52, the seesaw 51 is mounted on the positioning die 40 or the device frame 10 and extends into the positioning support cavity 41, the seesaw 51 is switched between a seesaw position and a lower pressing position relative to the positioning die 40 around a seesaw center line C arranged along the length or width direction of the device frame 10, the seesaw 51 has a tendency of being switched to the seesaw position, namely, the seesaw 51 is in the seesaw position extending into the positioning support cavity 41 in the initial state, and the contact terminal 52 is located below the seesaw 51; therefore, in the process of placing the product 200 to be pressed in the positioning support cavity 41, the product 200 to be pressed can push the seesaw 51 to switch from the seesaw position to the pressing position around the seesaw center line C very easily by virtue of the self-weight of the product 200, and the seesaw 51 at the pressing position is abutted against the contact terminal 52 to switch the on-off state of the touch switch 50, so that the touch switch 50 in the pressing device 100 of the invention enables the pushing force required when the touch switch 50 is triggered to be extremely small by virtue of the seesaw principle, thereby being suitable for occasions of light products 200 to be pressed and being used in different projects. Meanwhile, the touch switch 50 of the pressing device 100 of the present invention can be pushed by the light product to be pressed through the combination of the seesaw 51 and the contact terminal 52, so that the manufacturing cost of the pressing device 100 of the present invention is low.

It should be noted that the above-mentioned reference is established based on fig. 3, the length direction described above refers to the left-right direction in fig. 3, and the width direction described above refers to the front-back direction in fig. 3, but is not limited thereto.
