Description

Technical Field

[0001] This utility model belongs to the technical field of pressing pin equipment, specifically relating to a pressing pin equipment for photovoltaic heat sinks. Background Technology

[0002] A photovoltaic (PV) module is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Each PV cell has a limited power output and must be connected in series and packaged into a module to be used as a power source. Therefore, a PV module is the smallest, indivisible solar cell device capable of providing DC power output independently. A PV module mainly comprises nine core components: solar cells, interconnecting strips, busbars, tempered glass, EVA (electrical vapor cell), backsheet, aluminum alloy, silicone sealant, and junction box.

[0003] Chinese invention patent application number 202210014902.5 discloses a photovoltaic module heat sink, comprising a horizontally shaped rectangular plate, with multiple vertically shaped rectangular plates evenly distributed along the length of the horizontally shaped rectangular plate. The front vertical edge of the front vertically shaped rectangular plate forms the front edge of the heat sink, and the rear vertical edge of the rear vertically shaped rectangular plate forms the rear edge of the heat sink. The centerline of the horizontally shaped rectangular plate passes through the center of the vertically shaped rectangular plate. A horizontally shaped electric heating tape is disposed on the heat sink, with its centerline coinciding with the centerline of the horizontally shaped rectangular plate. The front and rear ends of the electric heating tape are flush with the front and rear ends of the heat sink. This photovoltaic module heat sink is typically installed and pressed in place using a pressing device. Chinese utility model patent application number 202322262982.9 discloses an automatic pressing mechanism, including a cam slide block, a drive assembly, and a follower assembly. The cam slide block has an inclined first sliding groove and a horizontally arranged second sliding groove, which are connected. The drive assembly is connected to the cam slide block and moves horizontally. The follower assembly includes a follower and a connecting block. The follower is connected to the connecting block and slidably connected within the first and second sliding grooves. When the follower moves into the second sliding groove, the connecting block abuts against the cam slide block, creating a gap between the follower and the bottom of the second sliding groove. This automatic pressing mechanism avoids the vertical movement and deformation of the follower, but the pressing head position cannot be moved arbitrarily and it is not suitable for photovoltaic heat sinks.

[0021] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0022] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0023] like Figure 1 and Figure 2 The photovoltaic heat sink pressing device shown mainly includes a matching base 1, a pressing installation mechanism 2, a control rotating arm mechanism 3, a transfer mechanism 4, a carrier plate 5, and a pressing mechanism 6.

[0024] The base 1 includes a support box 11, multiple casters 13 mounted on the bottom of the support box 11, and an operating platform 12 mounted on the top of the support box 11. A carrier plate 5 is mounted on the base 1, specifically on the operating platform 12, for placing the photovoltaic heat sink 1' (i.e., the photovoltaic heat sink 1' to be pressed). A pressing mechanism 2 is movably positioned above the carrier plate 5 for mounting a pressing mechanism 6. Two sets of control arm mechanisms 3 are mounted at the two corners of the operating platform 12 for combining with the adapter mechanism 4 to connect (or install) the pressing mechanism 2. Two sets of adapter mechanisms 4 are correspondingly connected to the pressing mechanism 2 and the two sets of control arm mechanisms 3. The pressing mechanism 6 is mounted on the pressing mechanism 2 for pressing the photovoltaic heat sink 1' below.

[0025] Specifically, each control arm mechanism 3 includes a column base 31 mounted on the base 1 (i.e., the operating platform 12 of the base 1), a column 32 with its lower end vertically inserted into the column base 31 (the column 32 and the column base 31 can be connected using conventional fasteners (such as bolts), a lower thrust ball bearing seat 30 mounted on the column 32, a lower thrust ball bearing fitted on the column 32 and supported on the lower thrust ball bearing seat 30, and an upper thrust ball bearing fitted on the column 32 and located above the lower thrust ball bearing. 33. A first locking nut 37 installed on the top of the column 32 and abutting against the upper thrust ball bearing 33, and a rotating arm unit rotatably sleeved on the column 32 and connecting the lower thrust ball bearing and the upper thrust ball bearing 33; since one end of the rotating arm unit is sleeved between the lower thrust ball bearing and the upper thrust ball bearing 33, thereby connecting the lower thrust ball bearing and the upper thrust ball bearing 33, the rotating arm unit can rotate around the axis of rotation of the column 32 using the lower thrust ball bearing and the upper thrust ball bearing 33 under the action of external force.

[0026] In this embodiment, the press pin mounting mechanism 2 includes two fourth bushings 21 spaced apart, two first side plates 23 connected to the sides of the two fourth bushings 21 and spaced apart (the two first side plates 23 are in the plane about the axis of the two fourth bushings 21), a first base plate connected between the two fourth bushings 21 and located on the bottom surface of the two first side plates 23 (the first base plate can be located below the two first side plates 23, or it can be located between the two first side plates 23 and below them), and a handle 22 mounted on the outer surface of any one of the first side plates 23 (the handle 22 is preferably mounted on the outer surface of the outer first side plate 23).

[0027] In this embodiment, the swing arm unit includes a first bushing 34 rotatably sleeved on the column 32 and connecting the lower thrust ball bearing seat 30 and the upper thrust ball bearing 33; a second bushing 38 disposed on one side of the first bushing 34 (the side close to the pressure pin mounting mechanism 2) (the axis of the first bushing 34 and the axis of the second bushing 38 are in a plane, which is defined as the first symmetry plane); two second side plates 35 connected to the sides of the first bushing 34 and the second bushing 38 and spaced apart (these two second side plates 35 are symmetrical about the aforementioned first symmetry plane); and a first top plate 36 connected between the first bushing 34 and the second bushing 38 and located on the top surface of the two second side plates 35 (the first top plate 36 can be on top of the two second side plates 35, or it can be located between the two second side plates 35 and on their upper part). As mentioned above: since one end of the swing arm unit is sleeved between the lower thrust ball bearing and the upper thrust ball bearing 33, thereby connecting the lower thrust ball bearing and the upper thrust ball bearing 33, the swing arm unit can rotate around the axis of the column 32 under the action of external force using the lower thrust ball bearing and the upper thrust ball bearing 33 as the rotation axis; specifically: since the first bushing 34 is connected to the lower thrust ball bearing and the upper thrust ball bearing 33 respectively, the first bushing 34 can be rotatably sleeved on the column 32, and under the action of external force, the entire swing arm unit can rotate relative to the column 32.

[0028] Each set of adapter mechanisms 4 includes a first rotating shaft 40 inserted at the outer end of the rotating arm unit, a second rotating shaft 44 inserted at one end of the pressure pin mounting mechanism 2, a second locking nut 46 installed at the bottom of the first rotating shaft 40 and the second rotating shaft 44, an electromagnetic brake 45 installed at the top of the first rotating shaft 40 and the second rotating shaft 44, and an adapter frame rotatably sleeved on the first rotating shaft 40 and the second rotating shaft 44; specifically, the adapter frame includes an angular contact ball bearing sleeved on the first rotating shaft 40 and the second rotating shaft 44 and located in the middle, a third bushing 41 rotatably sleeved outside the angular contact ball bearing, two third side plates 43 connected to the sides of the two third bushings 41 and spaced apart, and a second top plate 42 connected between the two third bushings 41 and located on the top surface of the two third side plates 43.

[0029] In this embodiment, the first rotating shaft 40 is inserted into the second bushing 38, and a second thrust ball bearing is installed between them. Specifically, the second thrust ball bearing is fitted onto the first rotating shaft 40, so that the second bushing 38 and the second thrust ball bearing are connected in a conventional manner. Thus, the rotating arm unit can rotate relative to the first rotating shaft 40 under the action of external force. The connection between the second rotating shaft 44 and the pressure pin mounting mechanism 2 is also the same, that is, it is connected through a third thrust ball bearing. Thus, under the action of external force, the pressure pin mounting mechanism 2 can rotate relative to the second rotating shaft 44. In addition, since angular contact ball bearings are installed between the third bushing 41 (one) and the first rotating shaft 40, and between the third bushing 41 (the other) and the second rotating shaft 44, the two third bushings 41 can rotate relative to the first rotating shaft 40 and the second rotating shaft 44 under the action of external force. At the same time, by energizing or de-energizing the electromagnetic brake 45, the rotation angle of the transfer mechanism 4 and the pressure pin mounting mechanism 2 can be controlled, thereby precisely controlling the position of the pressing mechanism 6.

[0030] The pressing mechanism 6 includes a servo electric cylinder 62 mounted on the pin mounting mechanism 2 (i.e., on the two first side plates 23), an adapter mounted on the lower end of the servo electric cylinder 62 and passing through the pin mounting mechanism 2, a pressure sensor 63 mounted on the lower end of the adapter, and a pressing die 61 mounted on the lower end of the pressure sensor 63. Thus, when the pressing die 61 acts on the pin, the pressure sensor 63 can sense the force applied by the pressing die 61 to the pin, ensuring the smooth operation of the pressing operation. By employing a control arm mechanism 3 with a specific structure in conjunction with the pin mounting mechanism 2, the adapter mechanism 4, and the pressing mechanism 6, the position of the pressing mechanism 3 can be manually moved to a relatively large extent for pressing the pins of the photovoltaic heat sink; moreover, the control arm mechanism 3 can withstand large external forces, significantly improving reliability and stability.

[0031] In this embodiment, the extrusion mechanism 6 further includes a sleeve 64 fitted on the lower die head 61, a support frame 65 mounted on the sleeve 64, a distance sensor 67 mounted on the support frame 65, and a bracket 68 mounted on the sleeve 64. Specifically, the extrusion mechanism 6 preferably also includes a light spot sensor 69 mounted on the bracket 68, so that a controller can be installed in the aforementioned support housing 11, and the controller can be connected to the electromagnetic brake 45, pressure sensor 63, distance sensor 67, light spot sensor 69 and servo electric cylinder 62 in a conventional manner (refer to the method disclosed in Chinese Invention Patent Application No. 202111138524.3). The pressure sensor 63, distance sensor 67 and light spot sensor 69 send signals to the controller, thereby controlling the electromagnetic brake 45 to be energized or de-energized to achieve braking and non-braking, and also controlling the servo electric cylinder 62 to work to achieve the pressing action to achieve the pressing pin.

[0032] The aforementioned photovoltaic heat sink pressing pin equipment has both manual and automatic modes. The preceding operations are the same in both manual and automatic modes: the operator grasps the handle 22 and pulls the pressing pin installation mechanism 2 so that the pressing die head 61 is aligned with the pin to be pressed.

[0033] When in manual mode, the electromagnetic brake 45 is activated, preventing the mechanisms from rotating relative to each other; when energized, the servo cylinder 62 is activated, driving the pressing die head 61 to press down the pin below.

[0034] When in automatic mode, the distance sensor 67 and the light spot sensor 69 work to obtain the distance between the pressing die head 61 and the pin, and send the corresponding signal to the controller. The controller sends a signal to the electromagnetic brake 45 to lock it, and sends a signal to the servo electric cylinder 62 to make it work. When the force it applies to the pin reaches the preset value (sensed by the pressure sensor 63), it stops working and resets.

[0035] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
