DETAILED DESCRIPTION

[0030] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] Reference Figure 1 and Figure 2The embodiment of the utility model discloses a hot pressing device, including: a hot pressing component 1, used for hot pressing a product 9 to be hot pressed, wherein the product 9 to be hot pressed includes a protective film and a back plate; an in-position sensing module 2, used for sensing whether the product 9 to be hot pressed is transmitted in place; a visual detection module, used for detecting position offset information of the product 9 to be hot pressed; an adjustment alignment component, connected to the hot pressing component 1, and the adjustment alignment component is used to adjust the position of the hot pressing component 1 according to the position offset information of the product 9 to be hot pressed.

[0032] Specifically, the backplane is a conductive backplane, which is used to achieve conductive interconnection between multiple back-contact battery cells. When the back-contact battery cells are arranged on the backplane, the protective film is specifically located on the side of the backplane away from the back-contact battery cells. Through the hot pressing equipment provided by the utility model, the protective film and the backplane can be hot-pressed before the battery cells are arranged on the backplane to flatten the edges of the protective film, thereby avoiding the position offset of the positioning points on the protective film caused by the warping of the edges of the protective film, thereby avoiding the alignment accuracy of the conductive backplane containing the protective film and the battery cells being affected when the battery cells are arranged. In addition, by means of hot pressing, the effective flattening of the edges of the protective film can be ensured. Compared with the method of pressing down alone, after hot pressing, the edges of the protective film will not warp up again.

[0033] The hot pressing device also includes a transmission component 8, which is used to transmit the product to be hot pressed 9. The transmission component 8 can be a transmission belt. The transmission direction of the transmission component 8 when transmitting the product to be hot pressed 9 is as shown in FIG. Figure 1 and Figure 3 The direction indicated by the arrow D in the figure. The in-place sensing module 2 can use a sensor, such as a photoelectric sensor, a proximity sensor, etc. When the product 9 to be hot-pressed is transmitted, the product 9 to be hot-pressed is first transmitted a preset distance through the transmission component 8. If the in-place sensing module 2 does not sense the product 9 to be hot-pressed, the transmission component 8 continues to operate at a low speed, and the product 9 to be hot-pressed is slowly transmitted until the in-place sensing module 2 senses the product 9 to be hot-pressed, and the transmission component 8 stops working, and the product 9 to be hot-pressed is no longer transmitted forward. When the in-place sensing module 2 senses the product 9 to be hot-pressed, it means that the product 9 to be hot-pressed is in place. At this time, the in-place sensing module 2 will output an in-place signal. When the in-place sensing module 2 does not sense the product 9 to be hot-pressed, it means that the product 9 to be hot-pressed is not in place, and the in-place sensing module 2 has no signal output.

[0034] The visual inspection module includes a visual camera 3 and a visual controller electrically connected to the visual camera 3. The visual camera 3 is used to capture the image of the product 9 to be hot pressed, and the visual controller is used to determine the actual position information of the product 9 to be hot pressed according to the image of the product 9 to be hot pressed captured by the visual camera 3, and compare the actual position information of the product 9 to be hot pressed with the preset standard position information of the product 9 to be hot pressed to determine the position offset information of the product 9 to be hot pressed. After the visual controller determines the position offset information of the product 9 to be hot pressed, it will be sent to the control module. Among them, the preset standard position information is also the information of the standard position that the product to be hot pressed should reach after being transmitted in place, but in the actual transmission process, the actual position of the product to be hot pressed will be offset, therefore, it is necessary to detect the actual position of the product to be hot pressed by the visual inspection module compared with the offset of the standard position. The number of visual cameras 3 can be set according to actual needs, such as two, four, six, etc. The number of visual cameras 3 is preferably set to four, and the four visual cameras 3 are respectively used to capture the images of the four corners of the product 9 to be hot pressed.

[0035] After the hot pressed product 9 is transferred to the right position, the position offset information of the hot pressed product 9 is detected by the visual detection module, so that the alignment adjustment component adjusts the position of the hot pressed component 1 according to the position offset information of the hot pressed product 9, so as to ensure that the position of the hot pressed component 1 corresponds to the position of the hot pressed product 9. The alignment adjustment component is specifically used to adjust the position of the hot pressed component 1 along a first direction and a second direction, the first direction is perpendicular to the second direction, the first direction is parallel to the transmission direction of the hot pressed product, and the first direction can refer to Figure 2 The direction indicated by the arrow A in the middle, the second direction can refer to Figure 3 It should be noted that the delivery of the hot pressed product 9 to the designated location means that the hot pressed product 9 has arrived within the predetermined area, which is a preliminary position control of the hot pressed product 9, while the visual inspection module detects the position offset information of the hot pressed product 9 to perform precise position detection.

[0036] In order to solve the problem of the edge of the protective film warping, the edge of the protective film can be manually flattened, but this method has problems such as low automation, cumbersome operation, low work efficiency, and inability to parallel production. Compared with the method of manually flattening the edge of the protective film, the utility model can automatically flatten the edge of the protective film, with a high degree of automation, improved work efficiency, and can achieve parallel production. In addition, in the embodiment of the utility model, the initial position control of the product 9 to be hot pressed can be achieved through the in-place sensing module 2, the precise positioning of the product 9 to be hot pressed can be achieved through the visual detection module, and the position of the hot pressing assembly 1 can be automatically adjusted according to the position offset information of the product 9 to be hot pressed, so as to ensure that the position of the hot pressing assembly 1 corresponds to the position of the product 9 to be hot pressed, thereby improving the hot pressing accuracy.

[0037] Reference Figure 1 and Figure 2 The hot pressing assembly 1 includes at least one hot pressing subgroup 11, and the at least one hot pressing subgroup 11 is used for hot pressing at least one side edge of the protective film.

[0038] Specifically, the protective film has four edges, and the positioning points on the protective film are arranged on at least one side edge of the protective film. The positioning points on the protective film are preferably arranged on one side edge of the protective film. Taking the edge on which the positioning points are arranged on the protective film as the first edge, when the hot pressing assembly 1 includes a hot pressing subgroup 11, the hot pressing subgroup 11 is used for hot pressing the first edge of the protective film. When the hot pressing assembly 1 includes two hot pressing subgroups 11, one of the hot pressing subgroups 11 is used for hot pressing the first edge of the protective film, and the other hot pressing subgroup 11 is used for hot pressing the second edge of the protective film corresponding to the first edge.

[0039] When the hot pressing assembly 1 includes three hot pressing subgroups 11, the three hot pressing subgroups 11 are respectively used for hot pressing the three side edges of the protective film, and the three side edges include the first edge. When the hot pressing assembly 1 includes four hot pressing subgroups 11, the four hot pressing subgroups 11 are respectively used for hot pressing the four edges of the protective film. In the embodiment of the utility model, the hot pressing assembly 1 only needs to hot press the edge of the protective film, and there is no need to hot press the entire product to be hot pressed, which saves costs.

[0040] The hot pressing subgroup 11 includes a plurality of hot pressing mechanisms 111 arranged at intervals, and at least one side edge of the protective film has a positioning point. During hot pressing, the orthographic projections of the plurality of hot pressing mechanisms 111 in the hot pressing subgroup 11 on the protective film do not overlap with the positioning point.

[0041] Specifically, the number of hot pressing mechanisms 111 in a single hot pressing subgroup 11 can be set according to actual needs, such as two, three, four, etc. The hot pressing assembly 1 preferably includes four hot pressing subgroups 11, and the number of hot pressing mechanisms 111 in a single hot pressing subgroup 11 is preferably three, so the hot pressing assembly 1 includes twelve hot pressing mechanisms 111 in total.

[0042] The positioning point on the protective film is preferably set on one side edge of the protective film, and the edge of the protective film on which the positioning point is set is taken as the first edge. Then, during hot pressing, the orthographic projections of the multiple hot pressing mechanisms 111 in the hot pressing subgroup 11 used for hot pressing the first edge of the protective film on the protective film do not overlap with the positioning point. Hot pressing specifically refers to the time when the hot pressing mechanism 111 contacts the product 9 to be hot pressed to perform hot pressing on the product 9 to be hot pressed. In the embodiment of the utility model, by setting the orthographic projections of the multiple hot pressing mechanisms 111 in the hot pressing subgroup 11 on the protective film to not overlap with the positioning point during hot pressing, it is possible to avoid hot pressing of the hot pressing mechanism 111 on the positioning point, thereby avoiding deformation at the positioning point.

[0043] The hot pressing device provided in the embodiment of the utility model further comprises a temperature controller electrically connected to the hot pressing assembly 1 , and the temperature controller is used to control the hot pressing assembly 1 to be powered on when the hot pressing device is started, so as to preheat the hot pressing assembly 1 .

[0044] Specifically, the temperature controller is connected to the multiple hot pressing mechanisms 111 in the hot pressing assembly 1. The hot pressing mechanism 111 includes a heating element, and the temperature controller is electrically connected to the heating element in the hot pressing mechanism 111 through a switch element. The temperature controller is used to control the conduction and disconnection of the switch element, thereby controlling the power on and off of the heating element in the hot pressing mechanism 111. When the switch element is turned on, the heating element is powered on and starts to heat, and the temperature of the hot pressing mechanism 111 gradually rises. When the switch element is disconnected, the heating element is powered off and no longer heats. The switch element can be a relay.

[0045] When the hot pressing equipment starts running, the hot pressing component 1 is powered on for preheating, and then the transmission component 8 is started to transmit the product 9 to be hot pressed. After the product 9 to be hot pressed is in place, the position of the hot pressing component 1 is adjusted according to the position offset information of the product 9 to be hot pressed. After the position adjustment of the hot pressing component 1 is completed, hot pressing is performed. In the embodiment of the utility model, when the hot pressing equipment starts running, the hot pressing component 1 is preheated first, so that the temperature of the hot pressing component 1 has reached the temperature setting value when hot pressing is performed later, which saves the time of waiting for heating and improves work efficiency.

[0046] A temperature sensor is provided on the hot pressing assembly 1 , and the temperature sensor is used to monitor the temperature of the hot pressing assembly 1 .

[0047] Specifically, the hot pressing assembly 1 includes a plurality of hot pressing mechanisms 111, each of which is provided with a temperature sensor, which is used to monitor the temperature of the hot pressing mechanism 111, so as to control the power on and off of the hot pressing mechanism 111 according to the temperature of the hot pressing mechanism 111, so as to avoid the temperature of the hot pressing mechanism 111 being too high or too low. When the temperature of the hot pressing mechanism 111 reaches the temperature setting value, the heating element in the hot pressing mechanism 111 is powered off and no longer performs heating. When the temperature of the hot pressing mechanism 111 is lower than the temperature setting value, the heating element in the hot pressing mechanism 111 is powered on and continues to perform heating.

[0048] The temperature sensor is electrically connected to the temperature controller, and the temperature controller is used to determine whether the temperature of the hot pressing component 1 reaches the set temperature value before the hot pressing component 1 hot presses the product 9 to be hot pressed after the product 9 to be hot pressed is transferred to the right place.

[0049] Specifically, after the hot-pressed product 9 is transferred to the right position, the position of the hot-pressing component 1 is adjusted according to the position offset information of the hot-pressed product 9. After the position adjustment of the hot-pressing component 1 is completed, it is first determined whether the temperature of the hot-pressing component 1 reaches the set temperature value. If so, the hot-pressed product 9 is then hot-pressed by the hot-pressing component 1.

[0050] When the hot pressing component 1 is hot pressing the current product 9 to be hot pressed, the temperature of the hot pressing component 1 will decay because the temperature will be transmitted to the product 9 to be hot pressed when the hot pressing component 1 is in contact with the product 9. When the subsequent multiple products 9 to be hot pressed are hot pressed, it cannot be guaranteed that the temperature of the hot pressing component 1 will always be maintained at the set temperature value. Therefore, after the product 9 to be hot pressed is transferred to the right place, before the hot pressing component 1 is hot pressed on the product 9 to be hot pressed, it is necessary to determine whether the temperature of the hot pressing component 1 has reached the set temperature value. If it has not reached the set temperature value, continue heating to make the temperature of the hot pressing component 1 reach the set temperature value.

[0051] Determining whether the temperature of the hot pressing assembly 1 reaches the temperature setting value specifically refers to determining whether the temperatures of multiple hot pressing mechanisms 111 in the hot pressing assembly 1 have all reached the temperature setting value. For the hot pressing mechanism 111 that has not reached the temperature setting value, heating is continued so that the temperatures of the multiple hot pressing mechanisms 111 can all reach the temperature setting value. In the embodiment of the utility model, through the above-mentioned setting, it can be ensured that during each hot pressing, the temperatures of the multiple hot pressing mechanisms 11 in the hot pressing assembly 1 can all reach the temperature setting value.

[0052] The position sensing module 2 includes at least one photoelectric sensor.

[0053] Specifically, the number of photoelectric sensors in the in-place sensing module 2 can be set according to actual needs, such as one, two, three, etc. The in-place sensing module 2 preferably includes two photoelectric sensors, which can be spaced apart along the second direction. The photoelectric sensor is a non-contact sensor with high precision and fast response.

[0054] Reference Figure 4 The hot pressing equipment provided by the embodiment of the utility model also includes a control module, which is electrically connected to the in-place sensing module, the visual detection module, the adjustment alignment component and the temperature controller; the in-place sensing module is used to send an in-place signal to the control module when the product 9 to be hot pressed is transferred to the in-place position.

[0055] Specifically, the visual controller is electrically connected to the control module, and the visual controller communicates with the control module through the first communication module. After the visual controller determines the position offset information of the product 9 to be hot-pressed, it will send it to the control module. The control module communicates with the temperature controller through the fourth communication module, and when the temperature of the hot-pressing component 1 reaches the temperature setting value, the temperature controller will send a signal to the control module.

[0056] The alignment adjustment assembly includes a first adjustment mechanism and a second adjustment mechanism, wherein the first adjustment mechanism is used to adjust the position of the hot pressing assembly 1 along a first direction, and the second adjustment mechanism is used to adjust the position of the hot pressing assembly 1 along a second direction. The first adjustment mechanism includes a first motor and a first servo driver electrically connected to the first motor, and the first servo driver communicates with the control module through a second communication module. The second adjustment mechanism includes a second motor and a second servo driver electrically connected to the second motor, and the second servo driver communicates with the control module through a second communication module. The control module is used to send position instructions to the first servo driver and the second servo driver according to the position offset information of the product 9 to be hot pressed, so as to drive the first motor and the second motor to work and adjust the position of the hot pressing assembly 1.

[0057] The control module is also electrically connected to the transmission component 8. When the product 9 to be hot pressed is transferred into place, the in-place sensing module 2 senses the product 9 to be hot pressed and sends an in-place signal to the control module. When the control module receives the in-place signal, it means that the product 9 to be hot pressed has been transferred into place, and the control module will control the transmission component 8 to stop running and control the visual camera 3 to start taking pictures. The in-place signal sent by the in-place sensing module 2 can be a high-level signal. In the embodiment of the utility model, through the setting of the control module, automatic control of the visual detection module and the adjustment alignment component can be achieved; through the setting of the in-place sensing module 2 sending an in-place signal to the control module when the product 9 to be hot pressed is transferred into place, the control module can determine that the product 9 to be hot pressed has been transferred into place according to the in-place signal, so as to facilitate subsequent control.

[0058] The control module is also electrically connected to a touch screen, and the touch screen communicates with the control module specifically through a third communication module. The moving speed of the first adjustment mechanism and the second adjustment mechanism, the area range information of the hot-pressed product 9, the preset standard position information of the hot-pressed product 9, the size information of the hot-pressed product 9, the fixed compensation value, the temperature setting value, and the preset hot-pressing time can be set on the touch screen. Among them, the size information of the hot-pressed product 9 includes the length and width of the hot-pressed product 9. The operating status of the hot-pressing equipment can also be displayed on the touch screen, and the operating status of the hot-pressing equipment includes the power-on state, the ready state, the running state, the system alarm state, etc.

[0059] Reference Figure 1 and Figure 2 The hot pressing equipment provided in the embodiment of the utility model also includes a movable seat 4 connected to at least one hot pressing subgroup 11, and an adjustment alignment component is connected to the movable seat 4. The adjustment alignment component is used to drive the movable seat 4 to move along a first direction and a second direction. The first direction is perpendicular to the second direction, and the first direction is parallel to the transmission direction of the product 9 to be hot pressed.

[0060] Specifically, the alignment adjustment assembly includes a first adjustment mechanism and a second adjustment mechanism, wherein the first adjustment mechanism is used to adjust the position of the movable seat 4 along the first direction, and the second adjustment mechanism is used to adjust the position of the movable seat 4 along the second direction. Through the setting of the movable seat 4, at least one hot pressing subgroup 11 can be driven to move together to adjust the position of the hot pressing assembly 1 as a whole, and the position adjustment of the hot pressing assembly 1 is fast and convenient.

[0061] Reference Figure 2 and Figure 3 The movable seat 4 is connected to the movable frame 5 , and the multiple hot pressing mechanisms 111 in each hot pressing subgroup 11 can be detachably connected to the movable frame 5 .

[0062] Specifically, the movable seat 4 and the movable frame 5 are both located above the transmission assembly 8. The movable frame 5 may include two first mounting rods 51, two second mounting rods 52 and two connecting rods 53. The extension direction of the first mounting rod 51 is perpendicular to the extension direction of the second mounting rod 52, and the extension direction of the connecting rod 53 is parallel to the extension direction of the first mounting rod 51. Two hot pressing subgroups 11 are detachably connected to the two first mounting rods 51, and the other two hot pressing subgroups 11 are detachably connected to the two second mounting rods 52.

The second mounting rod 52 is detachably connected to the connecting rod 53, and the first mounting rod 51 is detachably connected to the two second mounting rods 52.

[0063] For products to be hot pressed of different lengths and widths, the position where the hot pressing mechanism 111 is connected to the mobile frame 5 can be manually adjusted to match products to be hot pressed of different sizes. In addition, for products to be hot pressed of different lengths and widths, the spacing between the two first mounting rods 51 and the spacing between the two second mounting rods 52 can also be manually adjusted.

[0064] The hot pressing device provided in the embodiment of the utility model further includes a fixed frame 6, on which the in-position sensing module 2 is arranged, and the position of the in-position sensing module 2 is fixed. The visual camera 3 can be installed on the mobile frame 5. It should be noted that after the mobile frame 5 moves, when the next product to be hot pressed is hot pressed, the mobile frame 5 will first return to the initial position.

[0065] Reference Figure 1 and Figure 2 The hot pressing device provided in the embodiment of the utility model further includes a lifting assembly 7 connected to the hot pressing assembly 1, and the lifting assembly 7 is used to drive the hot pressing assembly 1 to move toward or away from the product 9 to be hot pressed.

[0066] Specifically, the lifting assembly 7 includes a plurality of lifting mechanisms 71, and the plurality of lifting mechanisms 71 are respectively connected to a plurality of hot pressing mechanisms 111, and the hot pressing mechanisms 111 are connected to the moving frame 5 through the lifting mechanisms 71. The plurality of lifting mechanisms 71 are respectively used to drive the plurality of hot pressing mechanisms 111 to move toward or away from the product 9 to be hot pressed. The direction in which the lifting mechanisms 71 drive the hot pressing mechanisms 111 to move can be referred to Figure 1 The arrow in C shows the direction.

[0067] Reference Figure 5 The steps of hot pressing the protective film and the back plate using the hot pressing equipment provided by the embodiment of the utility model are as follows:

[0068] S1, start.

[0069] S2, configuring the length and width information of the product to be hot pressed and the preset standard position information of the product to be hot pressed.

[0070] S3, set the temperature setting value, and start preheating of the hot pressing component.

[0071] S4, the automatic hot pressing process starts.

[0072] S5, judging whether the product to be hot pressed is in place. If the control module receives the in-place signal, it means that the product to be hot pressed is in place. If the control module does not receive the in-place signal, it means that the product to be hot pressed is not in place.

[0073] After the product to be hot pressed is transferred to the right position, S6 is executed, where the visual inspection module determines the position offset information of the product to be hot pressed and sends the position offset information of the product to be hot pressed to the control module.

[0074] After the visual camera 3 takes an image of the product 9 to be hot pressed, it will be sent to the visual controller. The visual controller determines the actual position information of the product 9 to be hot pressed based on the image of the product 9 to be hot pressed taken by the visual camera 3, and compares the actual position information of the product 9 to be hot pressed with the preset standard position information of the product 9 to be hot pressed to determine the position offset information of the product 9 to be hot pressed.

[0075] S7, the control module controls and adjusts the alignment component according to the position offset information of the product to be hot-pressed, so that the hot-pressing component moves to the specified position.

[0076] S8, determining whether the temperature of the hot pressing component reaches a set value.

[0077] If the temperature of the hot pressing assembly has reached the set value, S9 is executed, and the control module controls the lifting assembly to work, so that the lifting assembly drives the hot pressing assembly to press down to perform hot pressing of the product to be hot pressed.

[0078] S10, determining whether the hot pressing time reaches a preset hot pressing time.

[0079] If the hot pressing time reaches the preset hot pressing time, S11 is executed, the control module controls the lifting component to work so that the lifting component drives the hot pressing component to move upward, and then the control module controls the transmission component to work so that the product to be hot pressed flows out.
