[0041] The PLC controller 510 controls the linkage of the first power member 210 and the second power member 310 by inputting a program to provide power for the entire hot pressing device. The control program is first written by a computer in the form of a ladder diagram and then burned into the PLC controller. The operation of all modules of the entire device is controlled by the PLC controller 510.

[0042] Reference Figure 2 The frame 100 is used to fix and support various components on the hot pressing device.

[0043] The base 110 is a basic platform for fixing various basic components on the hot pressing device. The base 110 includes a workbench 111 and two vertical plates 112, and the two vertical plates 112 are arranged on the workbench 111 in parallel.

[0044] The crossbeam 120 refers to a beam parallel to the workbench 111 and supported by two vertical plates 112 above the base 110, and the upper side refers to the upper side along the direction of the first direction X. The first direction X refers to the height direction of the hot pressing device relative to the illustrated position, and the direction of the first direction X is defined as upward, and the direction away from the first direction X is defined as downward, that is, the upper and lower directions of the relative position can be distinguished by the first direction X. The crossbeam 120 connects the two vertical plates 112, and there is a distance difference between the crossbeam 120 and the workbench 111. The hot pressing assembly 200 is fixed on the crossbeam 120, and the support assembly 300 is fixed on the workbench 111, so that there is a height difference between the hot pressing assembly 200 and the support assembly 300.

[0045] The hot pressing assembly 200 hot presses the workpiece of the clamping arm assembly 400 along the first direction X after being heated to a preset temperature.

[0046] Reference Figure 3 The hot pressing assembly 200 includes a first power member 210 and a hot pressing device 220 .

[0047] One end of the heat press 220 is connected to the first power member 210 , and the other end faces the clamping arm assembly 400 of the workbench 111 .

[0048] The first power member 210 is fixed on the crossbeam 120 to provide moving power for the hot press 220. The hot press 220 is fixed on the first power member 210 and moves with the first power member 210 to realize the hot pressing action. The first power member 210 can be pneumatically driven, motor-driven, or hydraulically driven, and no specific limitation is made here. In the illustration of this embodiment, pneumatic driving is taken as an example, and pneumatic driving uses compressed gas as the gas source for explanation, but it does not mean that it is limited to this. The first power member 210 includes a first driver 211 and a first guide rod 212. The first driver 211 is connected to a solenoid valve (not shown in the drawings), an air pipe (not shown in the drawings), and a pneumatic connector (not shown in the drawings). The solenoid valve is connected to the first driver 211 and is also fixed on the crossbeam of the frame. The pneumatic connector is installed at the interface between the first driver 211 and the solenoid valve. The air pipe connects the pneumatic components together, and the compressed gas enters the solenoid valve after being filtered by the air source processor. The solenoid valve is connected to the PLC controller 510, and the PLC controller 510 controls the connection or disconnection of the pressurized gas, thereby controlling the opening and closing of the gas in and out of the first driver 211. When the first driver 211 receives the gas, the first driver 211 drives the first guide rod 212 to move downward along the first direction X with the hot press 220 to achieve hot pressing. When the first driver 211 disconnects the gas from entering, the first driver 211 drives the first guide rod 212 to move upward along the first direction X with the hot press 220 to achieve resetting.

[0049] Reference Figure 4 The supporting assembly 300 includes a second power member 310 and a supporting member 320. The second power member 310 is a member fixed on the base 110 and provides a moving power for the supporting member 320.

[0050] The second power member of the support assembly 300 can move the clamping arm assembly 400 forward and backward along the second direction Y to the bottom of the hot pressing assembly 200 for hot pressing. The second direction Y refers to the length direction of the hot pressing device relative to the position shown in the figure. The direction of the second direction Y is defined as forward, and the direction away from the second direction Y is defined as backward. That is, the second direction Y can distinguish the front and rear directions of the relative position.

[0051] The support member 320 refers to a workpiece used to carry the clamping arm assembly 400 to be processed. The support member 320 can be a plate member or a block, which is not specifically limited here. A plurality of grooves 321 are provided on the support member 320. A plurality refers to two or more. The number of grooves is preferably an even number. According to the requirements, only one of the grooves 321 can be placed in a clamping arm assembly 400, or a clamping arm assembly 400 can be placed in each of the grooves 321, or other numbers of clamping arm assemblies 400 can be placed in the grooves of the plurality of grooves 321. The support member 320 is set at an initial position by default, and the initial position is a certain distance from the position where the hot pressing is performed. After the hot pressing is completed, the support member is reset to the initial position by the second power member. There is a certain distance from the hot pressing position, so that the support assembly 300 is closer to the operator, which is convenient for the operator to work, such as installing or removing the clamping arm assembly 400.

[0052] The second power member 310 can be driven by air pressure, motor or hydraulic pressure, which is not specifically limited here. In the diagram of the present embodiment, gas drive is taken as an example, and compressed gas is used as the gas source for illustration, but it is not limited to this. The second power member 310 includes a second driver 311 and a second guide rod 312. The second driver 311 is connected with a solenoid valve (not shown in the drawings), an air pipe (not shown in the drawings) and a pneumatic connector (not shown in the drawings). The solenoid valve is connected to the second driver 311 and is also fixed on the base 110. The pneumatic connector is installed at the interface between the second driver 311 and the solenoid valve. The air pipe connects the pneumatic components together, and the compressed gas enters the solenoid valve after being filtered by the air source processor. The other end of the solenoid valve is connected to the PLC controller 510, and the PLC controller 510 controls the connection or disconnection of the pressurized gas, thereby controlling the opening and closing of the gas entering and exiting the second driver 311, so as to realize the control of the on-off condition of the second driver 311. When the second driver 311 receives gas, the second driver 311 drives the second guide rod 312 to move the support member 320 backward along the second direction Y, pushes the support member 320 to the bottom of the hot press 220, and waits for the hot press 220 to hot press the clamping arm assembly 400 placed on the support member 320. When the second driver 311 cuts off the gas, the second driver 311 drives the second guide rod 312 to move forward along the second direction Y with the hot press 220 to reset the support member 320. The first power member 210 and the second power member 310 can share a power source, such as a compressed gas source.

[0053] Reference Figure 5The clamp arm assembly 400 includes a metal clip 410 and a gasket 420. The metal clip 410 is placed in the groove 321. The hot pressing assembly 200 and the support assembly 300 cooperate to form an indentation on the gasket 420 that extends roughly along the center line of the gasket 420. The metal clip 410 can be in the shape of a curved bar or a straight bar, and the gasket 420 placed in the metal clip 410 can also be in the shape of a curved bar or a straight bar. When the metal clip 410 and the gasket 420 are in the shape of a curved bar, the indentation extends roughly along the curved center line (i.e., the central axis) of the gasket 420. A bar refers to an object with a long and narrow shape with an aspect ratio greater than 3:1.

[0054] The gasket 420 is pre-installed in the metal clip 410, and the side of the gasket 420 facing the metal clip 410 is covered by the metal clip 410, while the side facing away from the metal clip 410 is exposed to the outside. The metal clip 410 is installed in the groove 321 on the support 320, and the exposed surface of the gasket 420 is pressed by the hot press 220, and a dent is formed in the middle of the strip gasket 420.

[0055] The control assembly 500 refers to a workpiece or system for controlling the movement of the hot pressing assembly 200 and the supporting assembly 300 in the hot pressing device.

[0056] Reference Figure 1 The control component 500 includes a PLC controller 510, which is electrically connected to at least two solenoid valves. If there are two solenoid valves, the two solenoid valves are electrically connected to the first power component 210 and the second power component 310 respectively. Therefore, the PLC controller 510 can control whether the first power component 210 and the second power component 310 are working.

[0057] In this embodiment, the overall operating principle is:

[0058] First, the PLC controller 510 controls the gas to enter the second driver 311, so that the second driver 311 works, and the second driver 311 drives the second guide rod 312 to move the support member 320 forward, and pushes the support member 320 to the bottom of the hot press 220. Next, the PLC controller 510 controls the gas to enter the first driver 211, so that the first driver 211 works, and the first driver 211 drives the first guide rod 212 to move downward along the first direction X with the hot press 220 heated to a preset temperature, and completes the hot pressing. Then, after the hot pressing is completed, the PLC controller 510 disconnects the gas entering the first driver 211, so that the first driver 211 drives the first guide rod 212 to move upward along the first direction X with the hot press 220, and the hot press 220 is reset. Finally, the PLC controller 510 disconnects the gas entering the second driver 311, so that the second driver 311 drives the second guide rod 312 to move backward along the second direction Y with the hot press 220, and the support member 320 is reset.

[0059] The technical solution provided in this embodiment has the following beneficial effects compared to the prior art: the metal clip 410 and the gasket 420 are directly hot-pressed on the gasket 420 by the heat press 220 to form an indentation, so as to concentrate the blade pressure when the clamping arm assembly 400 is assembled on the ultrasonic knife for use, thereby improving the efficiency of cutting and coagulation.

[0060] In an implementation provided by the present application, the first power member 210 includes a first driver 211 , and the first driver 211 is connected to one or more heat presses 220 .

[0061] In some embodiments, the first power member 210 includes a first driver 211 , and the first driver 211 is connected to a heat press 220 .

[0062] In some embodiments, the first power member 210 includes a first driver 211 , and the first driver 211 is connected to a plurality of heat presses 220 .

[0063] In the above two embodiments, no matter there is one or more heat presses 220 , one or more heat presses 220 are driven by a first driver 211 to move downward simultaneously to heat press the gasket 420 in the corresponding clamping arm assembly 400 .

[0064] In one embodiment provided in the present application, the first power member 210 includes a plurality of first drivers 211, each of the plurality of first drivers 211 is independently connected to a heat press 220; wherein the PLC controller 510 drives the heat presses 220 connected to the first drivers 211 to work simultaneously; or, the PLC controller 510 drives the heat presses 220 connected to the first drivers 211 to work individually or simultaneously.

[0065] In order to explain the solution to be expressed in this embodiment clearly, an example is taken in which the first power member 210 includes two first drivers 211 and the hot pressing assembly 200 includes two groups of hot presses 220, and the following description is made in conjunction with the accompanying drawings.

[0066] The first power member 210 includes two first drivers 211, one end of each first driver 211 is connected to a heat press 220, and the other end is electrically connected to the PLC controller 510. Therefore, the PLC controller 510 can control the two first drivers 211 to work simultaneously, that is, the two first drivers 211 drive the corresponding heat press 220 to press downward simultaneously. The PLC controller 510 can also control each of the two first drivers 211 to work independently, that is, the two first drivers 211 drive the corresponding heat press 220 to press downward independently, and the movements of the heat presses 220 do not interfere with each other.

[0067] In one embodiment provided in this application, refer to Figure 6-Figure 10 The support member 320 is provided with at least one group of clamping arm assemblies 400, and the number of each group is at least two; each group of hot presses 220 includes a hot pressing plate 221 and at least two stamping strips 221a or stamping strips 221b arranged on the hot pressing plate 221, and the positions of each stamping strip 221a correspond one by one to the indentation positions of each gasket 420 in the clamping arm assembly 400 installed in the groove 321.

[0068] The hot press plate 221 is a workpiece for forming an indentation on the gasket 420 .

[0069] There are various hot pressing structures of the hot press 220 and the support member 320. To make the meaning of this embodiment clear, two structures are used for explanation below.

[0070] The first structure:

[0071] Reference Figure 7 Three groups of clamping arm assemblies 400 are provided on the support member 320 , each group of clamping arm assemblies 400 includes two metal clips 410 and two gaskets 420 respectively disposed in each metal clip 410 , and the two metal clips 410 of each group are arranged along the second direction Y.

[0072] Reference Figure 6The hot press 220 includes two groups of hot press plates 221, each group of hot press plates 221 includes three stamping strips 221a, and each stamping strip 221a corresponds to a gasket 420. The stamping strip 221a refers to the workpiece that is in direct contact with the gasket 420 when the hot press plate 221 is hot pressed downward. The stamping strips 221a are placed parallel to the vertical plate 112, and the length of each stamping strip 221a is greater than or equal to each metal clip 410 in each group of clamping arm assemblies 400 arranged along the second direction Y, so that the stamping strips 221a can simultaneously hot press the gaskets 420 placed in each metal clip 410 in the same group.

[0073] The connection of compressed gas to the first driver 211 and the second driver 311 is controlled by the PLC controller 510. When the second driver 311 receives gas, the second driver 311 drives the second guide rod 312 to move the support member 320 backward from the initial position along the second direction Y, and pulls the support member 320 to the position directly below the hot press 220. After the travel switch detects that the second driver 311 is pulled back to the position directly below the hot press 220, it outputs a signal to the PLC controller 510 to control the first driver 211 to drive the hot press plate 221 of the hot press 220 to press down.

[0074] When the PLC controller 510 controls the compressed gas to enter the first driver 211, the first driver 211 drives the first guide rod 212 to move downward along the first direction X with the hot pressing plate 221 heated to a certain temperature, and the three groups of clamping arm assemblies 400 on the support 320 are simultaneously hot-pressed by the six stamping strips 221a on the hot pressing plate 221, and the gaskets 420 in each group of clamping arm assemblies 400 are respectively hot-pressed in the corresponding metal clamp 410. When the PLC controller 510 cuts off the gas entering the first driver 211, the first driver 211 drives the first guide rod 212 to move upward along the first direction X with the hot pressing plate 221, so as to achieve the reset of the hot pressing plate 221.

[0075] After the travel switch detects that the first driver 211 returns to the original position, it outputs a signal to the PLC controller 510 to control the second driver 311 to return to the initial position, and then removes the formed gasket 420, and the entire hot pressing process is completed. The clamping arm assembly 400 to be processed can be re-used.

[0076] In the first structure, six stamping strips 221a on a hot pressing plate 221 are used to simultaneously hot press the gaskets 420 in three groups of clamping arm assemblies 400. That is, the hot pressing plate 221 works once to hot press multiple groups of clamping arm assemblies 400, thereby batch processing multiple products and improving the production efficiency of the clamping arm assemblies 400.

[0077] The second structure:

[0078] Reference Fig.10 Two groups of clamping arm assemblies 400 are disposed on the support member 320 , and each group of clamping arm assemblies 400 includes two metal clips 410 and two gaskets 420 respectively disposed in each metal clip 410 , that is, four clamping arm assemblies 400 .

[0079] Reference Fig. 9 The hot press 220 includes two hot pressing plates 221, each of which includes two punching strips 221b, and each punching strip 221b corresponds to a gasket 420. The punching strip 221b refers to the gasket 420 in the metal clip 410 that is pressed against the gasket 420 when the hot pressing plate 221 is pressed downward.

[0080] The connection of compressed gas to the first driver 211 and the second driver 311 is controlled by the PLC controller 510. When the second driver 311 receives gas, the second driver 311 drives the second guide rod 312 to move the support member 320 backward from the initial position along the second direction Y, and pulls the support member 320 to the position directly below the hot press 220. After the travel switch detects that the second driver 311 is pulled back to the position directly below the hot press 220, it outputs a signal to the PLC controller 510 to control the first driver 211 to drive the hot press plate 221 of the hot press 220 to press down.

[0081] When the PLC controller 510 controls the gas to enter the first driver 211, the first driver 211 drives the first guide rod 212 to move downward along the first direction X with the two hot pressing plates 221 at the same time, and the two stamping strips 221b of each hot pressing plate 221 respectively press the gaskets 420 in the two corresponding metal clamps 410 to form an indentation. Or the first driver 211 drives the first guide rod 212 to move downward along the first direction X with only one of the two hot pressing plates 221, and presses the gasket 420 in the corresponding metal clamp 410 to form an indentation. When the PLC controller 510 cuts off the gas entering the first driver 211, the first driver 211 drives the first guide rod 212 to move upward along the first direction X with the two hot pressing plates 221, so as to reset the hot press 220.

[0082] After the travel switch detects that the first driver 211 returns to the original position, it outputs a signal to the PLC controller 510 to control the second driver 311 to return to the initial position, and then removes the formed gasket 420, and the entire hot pressing process is completed. The clamping arm assembly 400 to be processed can be re-used.

[0083] Preferably, refer to Figure 8 The two groups of heat presses 220 are controlled by two first drivers 211 respectively, that is, the two first drivers 211 respectively control the two heat presses 220, and each heat press 220 can perform heat pressing separately with two corresponding stamping strips 221b.

[0084] In the second structure, by dividing each hot pressing plate 221 into a plurality of stamping strips 221b, and the number of stamping strips 221b is the same as the number of groups of clamping arm assemblies 400, a better hot pressing effect with better consistency is achieved, thereby improving the yield of the clamping arm assemblies 400.

[0085] In some embodiments, reference Figure 5 The metal clip 410 is provided with an opening 411 , and the hot pressing plate 221 can pass through the opening 411 to perform hot pressing on the gasket 420 to form an indentation.

[0086] The opening 411 means that the metal clip 410 has an opening position above the first direction X connected thereto to accommodate the gasket 420 .

[0087] In an embodiment provided in the present application, one of the heat press 220 and the support member 320 is provided with a limit block and the other is provided with a groove for concave-convex cooperation for limiting, or one of the heat press 220 and the support member 320 is provided with a limit block, and the distance between the heat press 220 and the support member 320 is limited by the limit block.

[0088] In some embodiments, a limiting block 222 is disposed on the heat press 220 , the support member 320 is disposed in a limiting groove 323 corresponding to the limiting block 222 , and the first power member 210 drives the limiting block 222 to be inserted into the limiting groove 323 .

[0089] Reference Figure 6 and Figure 7 The limit block 222 refers to a stopper provided on the hot press 220, and is used to restrict the distance that the hot press 220 can move in the first direction X driven by the first power member 210, so as to prevent the hot press 220 from moving too far in the first direction X and damaging the structure of the metal clip 410.

[0090] The limiting groove 323 refers to a feature used to cooperate with the limiting block 222 to guide the movement position of the heat press 220 in the first direction X to prevent the heat press gasket 420 from failing in the metal clip 410 due to the incorrect alignment of the heat press 220 and the support member 320.

[0091] In this embodiment, the first power member 210 is used to drive the heat press 220 to move in the first direction X, so that the limit block 222 on the heat press 220 is snapped into the limit groove 323, and then the gasket 420 in the metal clamp 410 is hot pressed by the hot pressing plate 221 to improve the yield of hot pressing and reduce the scrap rate of the clamping arm assembly 400.

[0092] In some embodiments, the hot press 220 is provided with a limiting groove, and the support member 320 is provided with a limiting block corresponding to the limiting groove. The specific implementation scheme is similar to the previous embodiment and will not be described in detail.

[0093] In some embodiments, the support member 320 is provided with a stop block 324 , and the stop block 324 moves along the edge of the heat press 220 and abuts against the surface of the heat press 220 .

[0094] It is worth mentioning that in this embodiment, a protruding plate 221c is provided on the hot pressing plate 221, and the protruding plate 221c extends outward from the hot pressing plate 221 to the direction where the stamping strip 221b is provided, and the length of the protruding plate 221c in the second direction Y is smaller than the length of the hot pressing plate 221 in the second direction Y.

[0095] Preferably, both ends of the raised plate 221c in the second direction Y are respectively at a distance from the hot pressing plate 221, and the above distance can be equal to the thickness of the limit block 324, can be slightly larger than the thickness of the limit block 324, or can be slightly smaller than the thickness of the limit block 324.

[0096] Reference Fig. 9 and Fig.10 , the first power member 210 drives the hot press 220 to move in the first direction X until the limit block 324 is inserted into the recessed position formed by the protruding plate 221c and the hot press plate 221, and the gasket 420 in the metal clamp 410 is hot pressed by the hot press plate 221 to improve the hot pressing yield rate and reduce the scrap rate of the ultrasonic knife clamping arm assembly. Compared with the limit structure of the previous embodiment, it is simpler, but it is necessary to align the positions of the support member 320 and the hot press 220 before moving assembly and control.

[0097] In some embodiments, a stopper is provided on the heat press 220, and the stopper moves along the edge of the support member 320 and contacts the surface of the support member 320. The specific implementation scheme is similar to the previous embodiment and will not be described in detail.

[0098] In one embodiment provided in the present application, the first driver 211 is a cylinder, a hydraulic cylinder or a motor.

[0099] In one embodiment provided in this application, refer to Figure 6 and Fig. 9 The heat press 220 also includes a temperature sensor 223 and a heating rod 224, and the control component 500 also includes a temperature controller 520. One end of the heating rod 224 and the temperature sensor 223 is connected to the hot pressing plate 221, and the other end of the heating rod 224 and the temperature sensor 223 is connected to the temperature controller 520. The number of heating rods 224 is equal to the number of stamping strips 221a or stamping strips 221b, and they are arranged one by one. Each heating rod 224 heats the corresponding stamping strip 221a or stamping strip 221b.

[0100] After the hot pressing device is powered on, the cylinder gas pipe is connected to the gas source. After pressing the power switch, the working mode button should be turned to the automatic gear position. Then, the start switch of the first driver 211 is turned on respectively, and then the temperature controller 520 is turned on.

[0101] Preferably, in order to allow the heating rod 224 to transfer heat to the hot pressing plate 221 faster, a through hole / blind hole is provided in the hot pressing plate 221, and the heating rod 224 is placed in the through hole / blind hole. The position of each through hole / blind hole on the hot pressing plate 221 corresponds to the position of a stamping strip 221a or a stamping strip 221b, respectively, and the corresponding stamping strip 221a or a stamping strip 221b is heated by the heating rod 224 placed in the through hole / blind hole.

[0102] In this embodiment, by arranging the number of heating rods 224 and stamping strips 221a or 221b in one-to-one correspondence, the heat transfer speed of each stamping strip 221a or 221b on the hot pressing plate 221 is faster, and the degree of heating of each stamping strip 221a or 221b is equivalent, thereby reducing the problem of local excessive temperature or low temperature, and the temperature of the hot pressing plate 221 can be monitored in real time by the temperature sensor 223.

[0103] The temperature controller 520 is a component that controls the heating rod 224 to heat the hot pressing plate 221. The temperature controller 520 determines whether to perform subsequent actions of the hot pressing device according to whether the actual temperature detected by the temperature sensor 223 reaches the preset working temperature.

[0104] The temperature controller 520 can connect the temperature sensor 223 and the heating rod 224. The temperature sensor 223 detects the current temperature of the hot plate 221 and sends it to the temperature controller 520. The temperature controller 520 compares the current temperature of the hot plate 221 with the preset temperature. If it is lower than the preset temperature, the temperature controller 520 commands the heating rod 224 to continue heating the hot plate 221. If the temperature sensor 223 detects that the current temperature of the hot plate 221 reaches the preset temperature, the temperature controller 520 commands the heating rod 224 to stop heating the hot plate 221 and sends a command to the PLC controller 510. The PLC controller 510 commands the second power member 310 and the first power member 210 to work in sequence.

[0105] In this embodiment, the temperature controller 520 is used to automatically control the heating demand of the heat press 220, making the product more automated. After the temperature controller 520 is turned on, the display screen will display the real-time temperature of the heat press plate 221 and the set working temperature. It is worth noting that the heat pressing time and heat pressing depth can be adjusted according to actual needs to meet the heat pressing needs of different products.

Only when the actual temperature reaches the set working temperature can the PLC controller 510 determine to start the hot pressing process, that is, the temperature of the hot press plate 221 reaching the standard is a prerequisite for the hot pressing work to proceed, and this setting can avoid the irregular operation of the operator to mistakenly start the hot pressing process due to the temperature not reaching the standard.

[0107] In this embodiment, when the hot pressing assembly 200 includes a plurality of hot presses 220 , each hot press 220 can be controlled individually by providing a plurality of temperature controllers 520 corresponding to the plurality of hot presses 220 one by one.
